+

Introducation +

+

dsHelper contains a number of client-side functions designed to simplify data manipulation and analysis using DataSHIELD. Functions are grouped in the following families:

+
    +
  • Descriptive functions
    • +
  • Data manipulation functions
    • +
  • Utility functions
    • +
  • Functions for trajectory models
    • +
+

This vignette demonstrates the first three families of function. Functions to assist with trajectory/mixed effect analysis are described in a separate tutorial.

Data: simulated data based on LifeCycle variables +

+

To demonstrate these functions we will use remote simulated data for three cohorts: ALSPAC, BCG & BiB.

Data manipulation functions +

+
+

Rename variables with dh.renameVars() +

+

dh.renameVars allows you to change the names of one or more variables within a dataframe. For example, we can rename the variables “id”, and “ethnicity” with simpler names:

+
+dh.renameVars(
+  df = "data",
+  current_names = c("ethnicity", "father_socialclass"), 
+  new_names = c("race", "paternal_class"))
+
+ds.colnames("data")
+
## $alspac
+## [1] "id"               "age"              "sex"              "mother_education" "weight"           "race"            
+## [7] "paternal_class"  
+## 
+## $bcg
+## [1] "id"               "age"              "sex"              "mother_education" "weight"           "race"            
+## [7] "paternal_class"  
+## 
+## $bib
+## [1] "id"               "age"              "sex"              "mother_education" "weight"           "race"            
+## [7] "paternal_class"
+
+
+

Removing columns with dh.dropCols() +

+

dh.dropCols allows you to remove columns from a dataframe. The argument “type” allows you to specify whether to remove or to keep the provided variables. For example, we can remove the column “mat_ed”:

+
+dh.dropCols(
+  df = "data", 
+  vars = "mother_education", 
+  type = "remove")
+
+ds.colnames("data")
+
## $alspac
+## [1] "id"             "age"            "sex"            "weight"         "race"           "paternal_class"
+## 
+## $bcg
+## [1] "id"             "age"            "sex"            "weight"         "race"           "paternal_class"
+## 
+## $bib
+## [1] "id"             "age"            "sex"            "weight"         "race"           "paternal_class"
+

Alternatively, we can just to keep certain columns and remove everything else. In this example we keep the columns “sex”, “height_m” and “ivf”:

+
+dh.dropCols(
+  df = "data", 
+  vars = c("id", "age", "sex", "weight"), 
+  type = "keep")
+
+ds.colnames("data")
+
## $alspac
+## [1] "id"     "age"    "sex"    "weight"
+## 
+## $bcg
+## [1] "id"     "age"    "sex"    "weight"
+## 
+## $bib
+## [1] "id"     "age"    "sex"    "weight"
+
+
+

Creating strata of a variable with dh.makeStrata() +

+

A common scenario is when you have repeat measurements of a variable, but want to create individual versions of that variable within different age bands.

+

For example, you may have a dataset with repeat measurments of height between ages 2-18. However, you want to create a new variable which is height between ages 4-6. This is quite a long process in datashield, as it involves creating a number of subsets. It is also necessary to deal with situations where a subject has >1 observation within the specified period.

+

In the example below, we create two variables for child height measured between (i) ages 4-6 and (ii) ages 7-10. Where children have more than one observation in either window, we opt to take the earliest measurement. This behaviour is controlled by the argument “mult_action”. You can also choose to take (i) the latest variable, or (ii) the variable closest to a particular time point. Finally, within each band we choose to take values >= to the lowest band, and < the highest band. This behaviour is controlled by the argument “band_action”. See ?dh.makeStrata for more information on the available arguments.

+

In this example it runs quite quickly, however if you are using many cohorts with large datasets it can take a considerable amount of time (30 - 60 min).

+
+dh.makeStrata(
+  df = "data",
+  var_to_subset = "weight",
+  age_var = "age", 
+  bands = c(4, 6, 7, 10), 
+  mult_action = "earliest",
+  band_action = "ge_l", 
+  id_var = "id", 
+  new_obj = "height_data")
+
## Error in `left_join()`:
+## ! Join columns in `x` must be present in the data.
+## ✖ Problem with `cohort` and `suffix`.
+
+ds.colnames("height_data")
+
## $alspac
+## [1] "id"      "tmp_obj"
+## 
+## $bcg
+## [1] "id"      "tmp_obj"
+## 
+## $bib
+## [1] "id"      "tmp_obj"
+

The created dataset contains 5 variables: the id variable, two variables giving the height value within the specified bands (height_.6, height_.10) and two variables giving the age of measurement for these height variables (age.6, age.10).

+

We can then use ds.merge to join this dataframe back with our main data:

+
+ds.merge(
+  x.name = "data", 
+  y.name = "height_data", 
+  by.x = "id", 
+  by.y = "id", 
+  all.x = TRUE, 
+  newobj = "data")
+
+ds.colnames("data")
+
## $alspac
+## [1] "id"      "age"     "sex"     "weight"  "tmp_obj"
+## 
+## $bcg
+## [1] "id"      "age"     "sex"     "weight"  "tmp_obj"
+## 
+## $bib
+## [1] "id"      "age"     "sex"     "weight"  "tmp_obj"
+
+
+

Transforming continuous variable to interquartile range using dh.makeIQR() +

+

In some scenarios (e.g. when using an environmental exposures) we want to standardise a continuous variable by transforming it by its interquartile range. The formula is:

+

value(subject) / 75th percentile(sample) - 25th percentile(sample)

+

When using data from multiple cohorts there are two options for the denominator: (i) create IQR in each cohort using the interquartile range in that cohort, (ii) create IQR in each cohort by using the combined interquartile range across all cohorts. This is controlled by the argument type.

+

In this example we transform child weight. The created variable will have the suffix “iqr_c” if type is “separate” and “iqr_p” if type = “pooled”.

+
+dh.makeIQR(
+  df = "data",
+  vars = "weight",
+  type = "split",
+  new_obj = "data")
+
+ds.colnames("data")
+
## $alspac
+## [1] "id"           "age"          "sex"          "weight"       "tmp_obj"      "weight_iqr_s"
+## 
+## $bcg
+## [1] "id"           "age"          "sex"          "weight"       "tmp_obj"      "weight_iqr_s"
+## 
+## $bib
+## [1] "id"           "age"          "sex"          "weight"       "tmp_obj"      "weight_iqr_s"
+
+ds.summary("data$weight_iqr_s")

+
+

Removing objects from workspace using dh.tidyEnv() +

+

The DataSHIELD function ds.rm() allows you to remove single objects from your workspace. However, we may want to remove a number of objects at once. Use the argument type to choose whether to keep or remove the variables listed in vars. Here we chose to keep “data” and remove everything else.

+
+dh.tidyEnv(
+  obj = "data",
+  type = "keep")
+ +
## $alspac
+## $alspac$environment.searched
+## [1] "R_GlobalEnv"
+## 
+## $alspac$objects.found
+## [1] "data"
+## 
+## 
+## $bcg
+## $bcg$environment.searched
+## [1] "R_GlobalEnv"
+## 
+## $bcg$objects.found
+## [1] "data"
+## 
+## 
+## $bib
+## $bib$environment.searched
+## [1] "R_GlobalEnv"
+## 
+## $bib$objects.found
+## [1] "data"
+
+
+

Identifying column indices using dh.findVarsIndex +

+

There are some occasions when we need to do know what column a set of variables is. For example, the function ds.dataFrameSubset takes an input for the argument keep.cols a vector column positions.

+

Subsetting data frames by column number is highly susceptable to breaking (e.g if you change the order of steps in a script). This function allows you to identify the column numbers of a vector of column names, like so:

+
+indices <- dh.findVarsIndex(
+  df = "data",
+  vars = c("sex", "age", "weight"))
+
+indices
+
## $alspac
+## [1] 2 3 4
+## 
+## $bcg
+## [1] 2 3 4
+## 
+## $bib
+## [1] 2 3 4
+
+
+
+

Describing data +

+
+

Summarising data using dh.getStats() +

+

The DataSHIELD functions ds.summary and ds.table produce basic descriptive statistics. However, they have a number of limitations: the output is not in a very useable format, you can only specify one variable at a time, and they don’t provide some information that we will likely need in manuscripts (e.g. about missingness).

+

Here we describe multiple variables using dh.getStats():

+
+stats <- dh.getStats(
+  df = "data",
+  vars = c("age", "sex", "weight")
+)
+
+stats
+

The output is a list of two tibbles, corresponding to categorical and continuous variables. See the help file for a list of calculated figures and stats.

+
+
+

Extracting model coefficients using dh.lmTab +

+

When we run simple linear regression models in DataSHIELD, the coefficients are returned within a nested list. It can be a bit tricky to manually extract these (e.g. to create a table or a plot). This function extracts the coefficients from linear models and outputs them in a tibble. It can also handle mixed-effect models and will also return summaries of random effects.

+
+output <- ds.glm(formula = "weight~age", data = "data", family = "gaussian")
+
+dh.lmTab(
+  model = output, 
+  type = "glm_ipd", 
+  direction = "wide", 
+  ci_format  = "separate")
+
## Error: Assertion on 'model' failed. function (msg) 
+## msgs <<- c(msgs, msg).
+
+## Error: Assertion on 'model' failed. function () 
+## msgs.
+
+## Error: Assertion on 'model' failed. function () 
+## length(msgs) == 0.
+

For manuscripts we may want to include confidence intervals in brackets after the point estimate. We can specify this with the argument “ci_format”:

+
+dh.lmTab(
+  model = output, 
+  type = "glm_ipd", 
+  direction = "wide", 
+  ci_format  = "paste")
+
## Error: Assertion on 'model' failed. function (msg) 
+## msgs <<- c(msgs, msg).
+
+## Error: Assertion on 'model' failed. function () 
+## msgs.
+
+## Error: Assertion on 'model' failed. function () 
+## length(msgs) == 0.
+
+
+

Checking class of data using dh.classDiscrepancy() +

+

In an ideal world all variables would have the same class in every study. However due to mistakes in harmonisation (or your scripts!) this may not be the case. The can cause problems because many DataSHIELD functions require the input variable(s) to have the same class in all studies.

+

Using dh.classDiscrepancy we can produce a tibble summarising the class of variable(s) across multiple studies. If we leave the argument vars empty we check the class of all variables. The column “discrepancy” summarises whether there are differences across studies.

+
+disc <- dh.classDiscrepancy(df = "data")
+
+disc
+
## # A tibble: 6 × 5
+##   variable     discrepancy alspac  bcg     bib    
+##   <chr>        <chr>       <chr>   <chr>   <chr>  
+## 1 id           no          numeric numeric numeric
+## 2 age          no          numeric numeric numeric
+## 3 sex          no          numeric numeric numeric
+## 4 weight       no          numeric numeric numeric
+## 5 tmp_obj      no          numeric numeric numeric
+## 6 weight_iqr_s no          numeric numeric numeric
+
+
+

Checking non-missing data using dh.anyData() +

+

When we perform analyses with multiple cohorts, we may want to use the same set of covariates in all analyses. We can use dh.anyData() to check which cohortsh have at least some data on given variables.

+
+available <- dh.anyData(
+  df = "data",
+  vars = c("age", "sex", "weight"))
+
+available
+
## # A tibble: 3 × 4
+##   variable alspac bcg   bib  
+##   <chr>    <lgl>  <lgl> <lgl>
+## 1 age      TRUE   TRUE  TRUE 
+## 2 sex      TRUE   TRUE  TRUE 
+## 3 weight   TRUE   TRUE  TRUE
+
+
+
+

Creating a dataset for analysis using dh.defineCases() +

+

Before starting analysis we often want to restrict the dataset to subjects meeting certain criteria. In the first example, we create a vector indicating whether each subject has complete data on the set of variables age, sex and weight:

+
+dh.defineCases(
+  df = "data", 
+  vars = c("age", "sex", "weight"),
+  type = "all", 
+  new_obj = "data_on_all_vars")
+
+cases_all <- ds.table("data_on_all_vars")$output.list$TABLE_rvar.by.study_counts
+
+cases_all

##                 study
+## data_on_all_vars alspac   bcg   bib
+##               1  129681 12724 68864
+##               NA      0     0     0
+

The data we have here is not the best to illustrate this function, as there is no missing data.

+

We can also check whether subjects have available data on any of a set of variables:

+
+dh.defineCases(
+  df = "data", 
+  vars = c("age", "sex", "weight"),
+  type = "any", 
+  new_obj = "data_on_any_vars")
+
+cases_any <- ds.table("data_on_any_vars")$output.list$TABLE_rvar.by.study_counts
+
+ cases_any
+
##                 study
+## data_on_any_vars alspac   bcg   bib
+##               1  129681 12724 68864
+##               NA      0     0     0
+

Again, we can’t see the differences because all subjects have data on all variables. However, lets assume that we want to create an subset of our data restricted to participants with data on at least one of these variables. We can then use ds.dataFrameSubset in conjuncture with the vector we created:

+
+ds.dataFrameSubset(
+  df.name = "data", 
+  V1.name = "data_on_all_vars", 
+  V2.name = "1", 
+  Boolean.operator = "==", 
+  newobj = "complete_df")
+
+ds.dim("data")
+ds.dim("complete_df")
+

+
+

Miscellaneous functions +

+
+

Enabling auto-complete functionality within R Studio. +

+

When using R studio with native R, auto-complete suggestions will appear for variables within a data frame. However, by default these won’t appear for variables within a serverside data frame.

+

We can get round this by creating a local object with the same structure as the remote object. Once you have run this function, autocomplete options for the data frame “data” should now be available.

+
+dh.localProxy(df = "data", conns = conns)
+
+
+

Manually pooling estimates by meta-analysis +

+

Most of the time the meta-analysis functions in DataSHIELD (e.g. ds.glmSLMA) will be sufficient. However, you may sometimes need additional flexibility with meta-analysis. For example, currently ds.glmSLMA doesn’t return heterogeneity statistics.

+

This functions takes vectors of coefficients and standard errors from multiple cohorts and meta-analyses them.

+

First we fit a model in different cohorts and extract the coefficients:

+
+output <- ds.glmSLMA(
+  formula = "weight~age", 
+  dataName = "data", 
+  family = "gaussian")
+

Now we can use this object and to the meta-analysis manually:

+
+meta_analysed <- dh.metaManual(
+  model = output,
+  method = "ML")
+

The output consists of a list with two elements. The first element (“model”) is a list with the output from metafor. The length will be the number of variables meta-analysed:

+
+str(meta_analysed$model)

Introduction +

+
+

Overview +

+

This tutorial will demonstrate how to model trajectories in DataSHIELD using repeated measures data from multiple cohorts.

+

This tutorial draws on the following papers/tutorials:

+
    +

  1. Hughes, R., Tilling, K. & Lawlor, D. Combining longitudinal data from different cohorts to examine the life-course trajectory. Preprint available on medrxiv: https://doi.org/10.1101/2020.11.24.20237669

    2. +

  2. Tilling K, Macdonald-Wallis C, Lawlor DA, Hughes RA, Howe LD. Modelling childhood growth using fractional polynomials and linear splines. Ann Nutr Metab. 2014;65(2-3):129-38. https://doi.org/10.1159/000362695.

    3. +

  3. Centre for Multilevel Modelling online course. http://www.bristol.ac.uk/cmm/learning/online-course/

    4. +
+

You will use simulated data to replicate part of the analysis from Hughes et al. cited above. It would be helpful to read this tutorial in conjuncture with this paper.

+

Please note that not all the methods used in Hughes et al. are available in DataSHIELD. Currently it is not possible to do 1-stage meta-analysis of mixed effects models. All of these are in the pipeline and this tutorial will be extended when these methods become available.

+

Do spline models!

+
+
+

Data +

+

We will be working with simulated repeated measures data for four cohorts: (i) Alspac, (ii) BCG, (iii) Born in Bradford & (iv) Probit.

+
+
+

Aims of the analysis +

+

Our research aims for today are:

+
    +
  1. To model child weight trajectories over time for four cohorts
    2. +
  2. To model sex differences in weight trajectories
    3. +
  3. To combine these trajectories by 2-stage meta-analysis
    4. +
+

Let’s get started.

+
+
+
+

Installing and loading packages +

+

First you need to install some packages are used in tutorial. Even if you have previously installed them it is worth doing this again to ensure that you have the latest versions.

+

If prompted to update packages, select option ‘none’.

+

First install the package ‘remotes’ which contains the function ‘install_github’.

+
+#install.packages("remotes")
+library(remotes)
+
+#install_github("datashield/DSI")
+#install_github("datashield/dsBaseClient")
+#install_github("lifecycle-project/ds-helper", ref = "dev")
+#install.packages("DSMolgenisArmadillo")
+#install.packages("tidyverse")
+

Now we load these packages.

+ +

A couple of things to note:

+
    +

  1. I use a lot of the tidyverse packages as I find them very efficient and they make the code more readable. If any syntax is unclear just ask!

    2. +

  2. I also use a number of functions from a package called dsHelper. This was written by me and Sido Haakma to make analysis in DataSHIELD more straightforward. Any problems with these functions just let us know.

    3. +
+
+
+

Logging in and assigning data +

+

The simulated data is held on a remote server. To access it, you first request a ‘token’ which contains the login details. You then use this to login and assign the data.

We can check that this has worked. You should see that each cohort has one dataframe called “data”, which contains 7 variables.

We wont be using all of the variables today, however if you want to come back and use this data to try out more complicated models we’ll keep it online.

Part 1: Visualising the data +

+
+

Scatter plots of child weight by age +

+

Let’s start off by looking at our repeated measures weight data for each cohort. We can make scatter plots with age on the x-axis and weight on the y-axis.

+

Note that the values that you see are anonymised - they are a non-disclosive approximation of the original values.

+
+ds.scatterPlot(x = "data$age", y = "data$weight")
+
+

+
+
## [1] "Split plot created"
+

What are you initial thoughts about the data?

+
+
+

Mean observed weight by age +

+

Another way to visualise the weight data is to split child age into yearly intervals, and plot the mean on the y-axis with age on the x-axis (see Figure 2 from Hughes et al.).

+

First of all we need to calculate the mean values for weight at each yearly age band:

+
+mean_age <- dh.meanByGroup(
+    df = "data", 
+    outcome = "weight", 
+    group_var = "age")
+
+mean_age %>% print(n = Inf)
+
## # A tibble: 55 × 3

+## 54 probit    18 61.6 
+## 55 probit    19 61.0
+

Now we have the values locally, we can use any r package to plot these. I like to use ggplot:

+
+palette <- c("#264653", "#2a9d8f", "#E9C46A", "#F4A261", "#E76F51")
+
+mean_age.plot <- ggplot() + 
+  geom_line(data = mean_age, aes(x = age, y = mean, colour = cohort), linewidth = 0.8) +
+  scale_y_continuous(limit = c(0, 80), breaks = seq(0, 80, 20), expand = c(0, 0)) +
+  xlab("Child age") +
+  ylab("Observed weight (KG)") +
+  scale_colour_manual(values = palette)
+
+mean_age.plot
+
+

plot of chunk mean-by-age-plot-1

+
+

Q: Looking at these two plots, What are your initial thoughts about the pattern of weight change over time?

+
+
+

Describing the exposures +

+

DataSHIELD contains the functions ds.summary and ds.table which can be used to describe continuous and categorical variables. However, the output of these is a little tricky to work with. Instead we can use the function ‘dh.getStats’ to extract descriptives in a more usable format.

+
+stats <- dh.getStats(
+    df = "data", 
+    vars = "sex")
+
+stats
+
## $categorical
+## # A tibble: 0 × 10
+## # ℹ 10 variables: variable <chr>, cohort <chr>, category <chr>, value <dbl>, cohort_n <int>, valid_n <dbl>, missing_n <dbl>, perc_valid <dbl>,
+## #   perc_missing <dbl>, perc_total <dbl>
+## 
+## $continuous
+## # A tibble: 5 × 15
+##   variable cohort    mean std.dev perc_5 perc_10 perc_25 perc_50 perc_75 perc_90 perc_95 valid_n cohort_n missing_n missing_perc
+##   <chr>    <chr>    <dbl>   <dbl>  <dbl>   <dbl>   <dbl>   <dbl>   <dbl>   <dbl>   <dbl>   <dbl>    <dbl>     <dbl>        <dbl>
+## 1 sex      alspac    0.49     0.5      0       0       0       0       1       1       1  129681   129681         0            0
+## 2 sex      bcg       0.48     0.5      0       0       0       0       1       1       1   12724    12724         0            0
+## 3 sex      bib       0.49     0.5      0       0       0       0       1       1       1   68864    68864         0            0
+## 4 sex      probit    0.48     0.5      0       0       0       0       1       1       1  191224   191224         0            0
+## 5 sex      combined  0.49     0.5      0       0       0       0       1       1       1  402493   402493         0            0
+

This gives us a list with two elements corresponding to the continuous and categorical variables. As we didn’t request stats for any continuous variables, the first list is empty.

+
+
+

Some more descriptives that are useful to have +

+

There are other bits of information it is useful to report:

+
    +
  • Total number of observations
    • +
  • Total number of participants
    • +
  • Min and max age of participants
    • +
  • Median number of measurements per individual
    • +
+

We can use the function dh.getRmStats to extract this info. Note that the min and max ages are based on the 5th and 95th percentiles as DataSHIELD doesn’t will not return true minimum and maximums due to disclosure issues.

+
+rm_stats <- dh.getRmStats(
+    df = "data",
+    outcome = "weight",
+    id_var = "id", 
+    age_var = "age")
+
+rm_stats
+
## # A tibble: 5 × 8

Part 2: Fitting a simple linear trajectory +

+
+

Trajectory models: prep +

+

Before we can get started, we need to make sure that our id variable is an integer. If we don’t, it breaks. First we create a new object which is an integer version of our ID. We then join this back to our main dataframe.

+
+ds.asInteger(
+    x.name = "data$id", 
+    newobj = "id_int")
+
+ds.dataFrame(
+    x = c("data$id", "data$age", "data$sex", "data$ethnicity", 
+          "data$father_socialclass", "data$mother_education", "data$weight",
+          "id_int"),
+    stringsAsFactors = F,
+    newobj = "data")
+
+
+

Specifying the model +

+

First we fit a model with weight predicted by four terms: an intercept (1), age, sex and the interaction between age and sex. These terms are our ‘fixed effects’, and comprise the first half of the formula below. They are specified in the same way as you would write a formula in a standard regression model.

+

In the second half of the formula below we specify our random effects. This is where we provide information about how we believe the data to be clustered.

+

The variable to the right of the vertical line is our ID variable. This specifies that we want to treat each invidual as a separate cluster, because we believe their measurements will be correlated. This is a plausible hypothesis: for example if my height is a lot higher than average at age 5, it is likely to also be higher than average at age 10. We can describe this as a 2-level clustering, with weight measurements (level 1) clustered within individuals (level 2).

+

The variables to the left of the vertical line specify which extra parameters we want to estimate for each individual. Or to put it another way, it specifies which parameters we allow to vary for each individual.

+

If we just specify “1”, then in addition to calculating an overall intercept, we also calculate an intercept for each individual. This provides us with information about the variability between individuals in their starting weight. This is called a random intercept model.

+

If we specifed “1 + age”, then in addition we would calculate a separate slope for each individual. This would provide us with information about how the gradient of the trajectory varies between individuals. This is called a random slope model.

+

Here we start with a random intercept model. Understand what you are doing is the difficult bit; fitting the model is straightfoward:

+

+    dataName = "data",

A neater way +

+

I find these objects a little fiddly to work with (you may not). You can also use the dsHelper function to extract the coefficients.

+
+model1.coef <- dh.lmTab(
+    model = model1.fit, 
+    type = "lmer_slma", 
+    coh_names = names(conns), 
+    ci_format = "separate", 
+    direction = "wide")
+

Let’s explore there in more detail

+
+

Fixed effects +

+

The fixed effects are analogous to your coefficients from a linear regression model.

If we use dh.lmTab it allows us to manipulate our output more easily. For example you might want to split the fixed effects by cohort:

+
+model1.coef$fixed %>% group_by(cohort) %>%
+group_split()
+

Or you might want to just select the pooled results:

+model1.coef$fixed %>% dplyr::filter(cohort == "combined")

+## 4 combined age:sex   -0.1   0.06     NA 402493     4 -0.22  0.02
+
+
+

Random effects +

+

When the model if fit, group (level 2) residuals are calculated for each subject. These represent the difference between interecept of each subject and the mean intercept for the sample.

+

However, there are not returned by DataSHIELD as they could be disclosive. Instead we can view the standard deviation of these residuals:

+
+model1.coef$random
+
## # A tibble: 8 × 5
+##   cohort group    var1      var2  stddev
+##   <chr>  <chr>    <chr>     <chr>  <dbl>
+## 1 alspac id_int   intercept <NA>    3.84
+## 2 alspac Residual <NA>      <NA>    5.63
+## 3 bcg    id_int   intercept <NA>    1.12
+## 4 bcg    Residual <NA>      <NA>    1.92
+## 5 bib    id_int   intercept <NA>    0.78
+## 6 bib    Residual <NA>      <NA>    1.91
+## 7 probit id_int   intercept <NA>    1.84
+## 8 probit Residual <NA>      <NA>    4.53
+

If we take ALSPAC as an example, we have an overall (mean) intercept of 3.87, and a standard deviation of 3.84. This indicates considerable variability between individual intercepts. If you had specified more than one random effect (e.g. slope) this would also be displayed here. We can also see the standard deviation of the residual error, ie the difference between observed values and predicted values within subject.

+
+
+
+

Plotting the trajectories +

+

In order to plot trajectories, we first need to get model predicted values of weight. In order to do this, we need to create a dataframe with the values of the fixed effects at which we want to predict values of weight. The names of the columns of this new dataframe need to correspond to the names of the coefficients in the output above.

+

We want to visualise the trajectories for both males and females between ages 0 and 25. In our reference dataframe, we therefore create values for age between 0 and 25 at 0.1 intervals, repeated for sex == 0 (males) and sex == 1 (females).

+
+new_data_m <- tibble(
+    age = seq(0, 25, by = 0.1), 
+    "age:sex" = age*0,
+    sex = 0)
+
+new_data_f <- tibble(
+    age = seq(0, 25, by = 0.11), 
+    "age:sex" = age*1,
+    sex = 1)
+
+pred_data <- bind_rows(new_data_m, new_data_f)
+

If we look at this object we have created, it has all the values of the model variables at which we want to predict weight:

+
+pred_data
+
## # A tibble: 479 × 3
+##      age `age:sex`   sex
+##    <dbl>     <dbl> <dbl>
+##  1   0           0     0
+##  2   0.1         0     0
+##  3   0.2         0     0
+##  4   0.3         0     0
+##  5   0.4         0     0
+##  6   0.5         0     0
+##  7   0.6         0     0
+##  8   0.7         0     0

+## 10   0.9         0     0
+## # ℹ 469 more rows
+

We can then use this reference data and our model object to get predicted values. Note that we now have four more columns appended to our reference data containing predicted values, standard error of predictions and confidence intervals.

+
+plotdata <- dh.predictLmer(
+    model = model1.fit,
+    new_data = pred_data,

Nice, we’re getting there. One thing to address is that currently we have predicted values for all cohorts between ages 0 and 25. However many of the cohorts don’t have data between those ages, so we might not want to plot beyond where there is data. We can trim our predicted data to the available ages.

+
+plot_trim <- dh.trimPredData(
+    pred = plotdata,
+    coh_names = c("alspac", "bcg", "bib", "probit", "combined"),

+

Next we set sex as a factor to make the plot clearer:

+
+plot_trim <- plot_trim %>%
+mutate(sex = factor(sex, levels = c(0, 1), labels = c("Male", "Female")))
+

It would also be nice to be able to overlay the predicted trajectory with the observed values. Remember earlier we made a scatter plot using DataSHIELD? We can extract the anonymised values which were used in that plot and store them as a local object. This allows us to build more flexible plots.

+

Each row of the created object represents the anomyised values of a subject.

+
+observed <- dh.getAnonPlotData(
+    df = "data",
+    var_1 = "age", 
+    var_2 = "weight")
+
+observed
+
## # A tibble: 804,986 × 3

+## # ℹ 804,976 more rows
+

Now we are ready to plot the pooled trajectories. We use the function “sample_frac” to only take 1% of the observed values. You can play around with this value, but if you use too many the graph becomes unreadable.

+
+ggplot() + 
+  geom_point(
+    data = sample_frac(observed, .01) %>% dplyr::filter(cohort == "combined"), 
+    aes(x = age, y = weight), 
+    alpha = 0.4, 
+    size = 0.1) +
+  geom_line(
+    data = plot_trim %>% dplyr::filter(cohort == "combined"), 
+    aes(x = age, y = predicted, colour = sex), size = 0.8) +
+  geom_ribbon(
+    data = plot_trim %>% dplyr::filter(cohort == "combined" & sex == "Male"), 
+    aes(x = age, ymin = low_ci, ymax = upper_ci), alpha = 0.1) +
+  geom_ribbon(

+  xlab("Child age") +

+
+

We can also plot the trajectories for each cohort separately:

+  geom_point(
+    data = sample_frac(observed, .01) %>% dplyr::filter(cohort != "combined"), 
+    aes(x = age, y = weight),

+  ylab("Predicted weight (KG)") +
+  labs(colour = "Sex")
+
+

+
+

Q: Looking at the plots, how well do you think our model fits the data?

+
+
+
+

Part 3: Fitting a non-linear trajectory using a transformation of the age term +

+

The previous model doesn’t look great to me, especially around age 5 where there looks to be a distinct non-linearity in the trajectory which we are not capturing.

+

One way to address this is to model weight not as a function of age, but as a function of a transformation of age.

+

Let’s start by creating a new variable which is age^2, and see if this provides a better fit. We create the variable, and join it back in our main data frame.

+
+ds.make(
+    toAssign = "data$age^2", 
+    newobj = "age_2")
+
+ds.dataFrame(
+    x = c("data", "age_2"), 
+    newobj = "data")
+

Now we are going to simply repeat the steps before, but using this transformed variable instead of the original age variable.

+

First we run the model:

+
+age_2.fit <- ds.lmerSLMA(
+    dataName = "data",
+  formula = "weight ~ 1 + age_2 + sex + age_2*sex + (1|id_int)", 
+  datasources = conns)
+

Now we create a dataframe of the values of the fixed effects at which we want to predict weight. Note that as we have transformed our age term, we need to add this transformed version of the variable to our reference data.

+
+pred_ref_2a <- tibble(
+    age = seq(0, 25, by = 0.1), 
+    age_2 = age^2,
+    "age_2:sex" = age_2*0,
+    sex = 0)
+
+pred_ref_2b <- tibble(
+    age = seq(0, 25, by = 0.11), 
+    age_2 = age^2,
+    "age_2:sex" = age_2*1,
+    sex = 1)
+
+pred_ref_2 <- bind_rows(pred_ref_2a, pred_ref_2b)
+

Again we get the predicted values, trim them at the ages of the observed data and set sex as a factor.

+
+pred_data_2 <- dh.predictLmer(
+    model = age_2.fit,
+    new_data = pred_ref_2,
+    coh_names = names(conns))
+
+pred_data_2_trim <- dh.trimPredData(
+    pred = pred_data_2,
+    coh_names = c("alspac", "bcg", "bib", "probit", "combined"),
+    min = rep(0, 5), 
+    max = c(20, 5, 5, 20, 20))
+
+pred_data_2_trim <- pred_data_2_trim %>%
+mutate(sex = factor(sex, levels = c(0, 1), labels = c("Male", "Female")))
+

Let’s plot this against the observed data and see if it fits any better:

+
+ggplot() + 
+  geom_point(
+    data = sample_frac(observed, .01) %>% dplyr::filter(cohort == "combined"), 
+    aes(x = age, y = weight), 
+    alpha = 0.4, 
+    size = 0.1) +
+  geom_line(
+    data = pred_data_2_trim %>% dplyr::filter(cohort == "combined"), 
+    aes(x = age, y = predicted, colour = sex), size = 0.8) +
+  scale_x_continuous(limit = c(0, 20), breaks = seq(0, 20, 5), expand = c(0, 0)) + 
+  scale_y_continuous(limit = c(0, 80), breaks = seq(0, 80, 20), expand = c(0, 0)) +
+  xlab("Child age") +
+  ylab("Predicted weight") +
+  labs(colour = "Sex")
+
+

plot of chunk plot-model-2

+
+

Hmmm. We now have a non-linear trajectory, but it still doesn’t look a great fit. We haven’t looked at any fit statistics or residuals yet, but from the eye it clearly doesn’t fit the data. It also doesn’t seem to capture the sex differences we would expect. We can do better than this.

+
+
+

Part 4: Fractional polynomials +

+

Using one transformation of age allowed one ‘bend’ in the trajectory. However, the problem we saw with the previous model is that natural growth trajectories often have multiple bends.

+

One way to model this is to use two transformations of age (e.g. age^2 and age^0.5). These are called fractional polynomials (powers which involve fractions). You could use more than 2 transformations: this would give you a better model fit, but with greater risk of overfitting your model. Here we will stick two.

+

Even with only two transformations of age, there are infinite number of possible combinations. How do we chose which to use?

+

You may have a good a priori reason to chose a combination of terms. If you don’t, one reasonable approach is to select a certain set of transformations, and fit every combination of those. We can then see which combination of age terms provides the best model fit.

+
+

Preparing the data for modelling +

+
+

Remove values of zero +

+

Transforming values of zero will create infinite values which will break our models. We add a small quantity to our age variable to avoid this.

+
+ds.assign(
+    toAssign = "data$age+0.01", 
+    newobj = "age", 
+  datasources = conns)
+
+dh.dropCols(
+    df = "data", 
+    vars = "age", 
+    type = "remove", 
+    new_obj = "data")
+
+ds.dataFrame(
+    x = c("data", "age"), 
+    newobj = "data")
+
+
+

Create transformations of age term +

+

We could do the transformations manually, but this would be a bit cumbersome. We can insted use the function ds.makeAgePolys to create transformations of age. Here we use the following powers: -2, -1, -0.5, log, 0.5, 2, 3.

+
+dh.makeAgePolys(
+    df = "data", 
+    age_var = "age", 
+    poly_names = c("m_2", "m_1", "m_0_5", "log", "0_5", "2", "3"), 
+    poly_form = c("^-2", "^-1", "^-0.5", "log", "^0.5", "^2", "^3"))
+

We can check this has worked, and see the mean values for these new variables.

+
+poly_summary <- dh.getStats(
+    df = "data", 
+    vars = c("agem_2", "agem_1", "agem_0_5", "age_log", "age0_5", "age2", "age3"))
+
+poly_summary$continuous %>%
+dplyr::select(cohort, variable, mean, std.dev) %>%
+print(n = Inf)
+

Identifying the best fitting model +

+

Ok, so now we have a load of transformations of our age in term in the dataframe “data”. Next we want to fit models for each paired combination of these terms. Again, we could do this by writing out ds.lmerSLMA 28 times, but this brings a fair chance that you make an error in the code.

+

I’ve written a couple more functions to streamline the process.

+
+

Create model formulae +

+

‘dh.makeLmerForm’ creates the model formulae based on the age terms you have created. The argument to “agevars” is a vector of variable names corresponding to the age transformations we created above.

+

First we try to find the best shape of trajectory, so we create model formulae just with the age terms.

+
+weight_form <- dh.makeLmerForm(
+  outcome = "weight", 
+  id_var = "id_int", 
+  age_vars = c("age", "agem_2", "agem_1", "agem_0_5", "age_log", "age0_5", "age2", "age3"), 
+  random = "intercept")
+
+weight_form %>% 
+head(10)
+
## # A tibble: 10 × 2
+##    polys           formula                               
+##    <chr[1d]>       <chr>                                 
+##  1 age,agem_2      weight~1+ age+agem_2 + (1|id_int)     
+##  2 age,agem_1      weight~1+ age+agem_1 + (1|id_int)     
+##  3 age,agem_0_5    weight~1+ age+agem_0_5 + (1|id_int)   
+##  4 age,age_log     weight~1+ age+age_log + (1|id_int)    
+##  5 age,age0_5      weight~1+ age+age0_5 + (1|id_int)     
+##  6 age,age2        weight~1+ age+age2 + (1|id_int)       
+##  7 age,age3        weight~1+ age+age3 + (1|id_int)       
+##  8 agem_2,agem_1   weight~1+ agem_2+agem_1 + (1|id_int)  
+##  9 agem_2,agem_0_5 weight~1+ agem_2+agem_0_5 + (1|id_int)
+## 10 agem_2,age_log  weight~1+ agem_2+age_log + (1|id_int)
+

This has created a table where each row (a total of 28) contains the formula for a mixed effects model with a different combination of the fractional polynomials.

+
+
+
+

Fit all combinations of polynomials +

+

The function dh.lmeMultPoly takes as an input to the argument “formulae” a vector of formulae. Here we use the formulae created above. You could also create your own vector of formulae and supply it to the same argument.

+

If you’ve read Rachel Hughes’ paper, you’ll notice that she first fits models on a discovery sample, and then checks the fit on the remaining sample. I’ve skipped this here for simplicity but it is possible to do this in DS.

+

This will take a few minutes as we are fitting 28 different models.

+
+poly.fit <- dh.lmeMultPoly(
+    df = "data",
+    formulae = weight_form$formula, 
+  poly_names = weight_form$polys)
+
## Error in dh.lmeMultPoly(df = "data", formulae = weight_form$formulae, : object 'weight_form' not found
+

There are some converegence warnings. We can see details here:

The output contains a table with the negative log likelihood for each model in each study, the average rank of that model across all studies and the summed negative log likelihood. The model with the lowest summed log-likelhood across studies contains two powers: age^0.5 & age^2.

In this scenario we are trying to fit the same model to all cohorts. In other scenarioes you might want to fit a different model to different cohorts. You could still use this table as a reference for the best fitting model, for example for alspac:

+
+poly.fit$fit %>%
+select(model, alspac) %>%
+arrange(desc(alspac))
+
## # A tibble: 28 × 2
+##    model          alspac

+
+
+

Final model +

+

Ok, so we’ve got an idea what the best fitting combination of age terms will be. Now we can fit our final model, including sex and the interaction with the age terms. We aren’t worrying about other covariates in this example, but of course you could include them.

+
+final.fit <- ds.lmerSLMA(
+    dataName = "data",
+  formula = "weight ~ 1 + age0_5 + age2 + sex + age0_5*sex + age2*sex + (1|id_int)")
+
+
+

Making plots +

+

Now we can go through the same process as above to make our plot. Again, we need to create our age transformations in the new data to get the predicted values for weight at each age.

+
+pred_ref_final_m <- tibble(
+    age = seq(0, 25, by = 0.1), 
+    age0_5 = age^0.5,
+    age2 = age^2, 
+    sex = 0,
+    "age0_5:sex" = age0_5*sex, 
+  "age2:sex" = age2*sex)
+
+pred_ref_final_f <- tibble(
+    age = seq(0, 25, by = 0.1), 
+    age0_5 = age^0.5,
+    age2 = age^2, 
+    sex = 1,
+    "age0_5:sex" = age0_5*sex, 
+  "age2:sex" = age2*sex)
+
+pred_ref_final <- bind_rows(pred_ref_final_m, pred_ref_final_f)
+

Again we get the predicted values, trim them at the ages of the observed data and set sex as a factor.

+
+pred_ref_final <- dh.predictLmer(
+    model = final.fit,
+    new_data = pred_ref_final,
+    coh_names = names(conns)
+)
+
+pred_ref_final_trim <- dh.trimPredData(
+    pred = pred_ref_final,
+    coh_names = c("alspac", "bcg", "bib", "probit", "combined"),
+    min = rep(0, 5), 
+    max = c(20, 5, 5, 20, 20)
+)
+
+pred_ref_final_trim <- pred_ref_final_trim %>%
+mutate(sex = factor(sex, levels = c(0, 1), labels = c("Male", "Female")))
+

And now we can make some plots

+
+ggplot() + 
+  geom_point(
+    data = sample_frac(observed, .01) %>% dplyr::filter(cohort == "combined"), 
+    aes(x = age, y = weight), 
+    alpha = 0.4, 
+    size = 0.1) +
+  geom_line(
+    data = pred_ref_final_trim %>% dplyr::filter(cohort == "combined"), 
+    aes(x = age, y = predicted, colour = sex), size = 0.8) +
+  geom_ribbon(
+    data = pred_ref_final_trim %>% dplyr::filter(cohort == "combined" & sex == "Male"), 
+    aes(x = age, ymin = low_ci, ymax = upper_ci), alpha = 0.1) +
+  geom_ribbon(
+    data = pred_ref_final_trim %>% dplyr::filter(cohort == "combined" & sex == "Female"), 
+    aes(x = age, ymin = low_ci, ymax = upper_ci), alpha = 0.1) +
+  scale_x_continuous(limit = c(0, 20), breaks = seq(0, 20, 5), expand = c(0, 0)) + 
+  scale_y_continuous(limit = c(0, 80), breaks = seq(0, 80, 20), expand = c(0, 0)) +
+  xlab("Child age") +
+  ylab("Predicted weight (KG)") +
+  labs(colour = "Sex")
+
+

+
+

We can also plot the trajectories by cohort

+
+ggplot() + 
+  geom_point(
+    data = sample_frac(observed, .01) %>% dplyr::filter(cohort != "combined"), 
+    aes(x = age, y = weight),

+    size = 0.1) +
+  geom_line(
+    data = pred_ref_final_trim %>% dplyr::filter(cohort != "combined"), 
+    aes(x = age, y = predicted, colour = sex), size = 0.8) +
+  geom_ribbon(
+    data = pred_ref_final_trim %>% dplyr::filter(cohort != "combined" & sex == "Male"), 
+    aes(x = age, ymin = low_ci, ymax = upper_ci), alpha = 0.1) +
+  geom_ribbon(
+    data = pred_ref_final_trim %>% dplyr::filter(cohort != "combined" & sex == "Female"), 
+    aes(x = age, ymin = low_ci, ymax = upper_ci), alpha = 0.1) +
+  facet_wrap(~cohort) +
+  scale_x_continuous(limit = c(0, 20), breaks = seq(0, 20, 5), expand = c(0, 0)) + 
+  scale_y_continuous(limit = c(0, 80), breaks = seq(0, 80, 20), expand = c(0, 0)) +
+  xlab("Child age") +
+  ylab("Predicted weight (KG)") +
+  labs(colour = "Sex")
+
+

+
+

Great, this looks like a much better fit. We have captured the initial growth, followed by a reduction in growth rate at age 5 followed by an increase into adolescence.

+

This model still isn’t perfect - looking at the graph what problem can you see?

+
+
+
+

Checking model fit +

+

The final step is to check how well the model fits at different age points. Here we can approximate Table 2 from Tilling et al. (2014) “Modelling Childhood Growth …”.

+

First we get mean observed values for weight between different age bands. The ‘intervals’ argument specifies how we want to bin our age variable. Again this takes a few minutes to run.

+
+observed_by_age <- dh.meanByGroup(
+    df = "data", 
+    outcome = "weight", 
+    group_var = "age", 
+    intervals = c(0, 1, 1, 2, 3, 5, 6, 10, 11, 15, 16, 18)
+)
+
+observed_by_age

We rename our column to ‘observed’:

+
+obs <- observed_by_age %>%
+dplyr::rename(observed = mean)
+

Now we get the average predicted values between the same age bands

+
+pred_by_age <- pred_ref_final_trim %>%
+mutate(
+    group = case_when(
+        age > 0 & age <= 1 ~ "0_1", 
+        age >= 1 & age <= 2 ~ "1_2", 
+        age >= 3 & age <= 5 ~ "3_5", 
+        age >= 6 & age <= 10 ~ "6_10", 
+        age >= 11 & age <= 15 ~ "11_15", 
+        age >= 16 & age <= 18 ~ "16_18")
+        ) %>%
+dplyr::filter(!is.na(group)) %>%
+group_by(group, cohort) %>%
+summarise(
+    predicted = round(mean(predicted), 2),
+    low_ci = round(mean(low_ci), 2),
+    upper_ci = round(mean(upper_ci), 2))
+
+pred_by_age
+
## # A tibble: 24 × 5
+## # Groups:   group [6]
+##    group cohort   predicted low_ci upper_ci
+##    <chr> <chr>        <dbl>  <dbl>    <dbl>

+## # ℹ 14 more rows
+

Finally we join the observed and predicted values into one table, and calculate the difference between the two. We can also use the confidence intervals to calculate upper and lower bounds of the residual. You can see that model fit isn’t great for PROBIT towards the extremes. For other cohorts, the looks pretty good.

+
+res_tab <- left_join(obs, pred_by_age, by = c("group", "cohort")) %>%
+mutate(
+    difference = round(observed - predicted, 2),
+    lower_res = round(observed - upper_ci, 2),
+    higher_res = round(observed - low_ci, 2),
+    group = factor(
+        group, 
+        levels = c("0_1", "1_2", "3_5", "6_10", "11_15", "16_18"),
+        ordered = TRUE), 
+    limits = paste0(lower_res, " to ", higher_res)) %>%
