Functions

for preparing the data for meta analyses

1) Subsetting data

Create function for sub-setting the data to choose only one data point per individual per trait: “data_subset_parameterid_individual_by_age”

data_subset_parameterid_individual_by_age <- function(mydata, parameter, age_min = 0, 
    age_center = 100) {
    tmp <- mydata %>% filter(age_in_days >= age_min, id == parameter) %>% # take results for single individual closest to age_center
    mutate(age_diff = abs(age_center - age_in_days)) %>% group_by(biological_sample_id) %>% 
        filter(age_diff == min(age_diff)) %>% select(-age_diff)  # %>% 
    # filter(!duplicated(biological_sample_id)) #Felix 6/2/2020: this line can
    # be deleted
    
    # still some individuals with multiple records (because same individual
    # appear under different procedures, so filter to one record)
    j <- match(unique(tmp$biological_sample_id), tmp$biological_sample_id)
    tmp[j, ]
}

2) “Population statistics”

Create function called: “calculate_population_stats” This function groups animals from the same strain and same insitiution together. This is done for each trait seoarately, and only for traits that have been measured in both sexes. Any group containing fewer than 5 individuals is excluded.

calculate_population_stats <- function(mydata, min_individuals = 5) {
    mydata %>% group_by(population, strain_name, production_center, sex) %>% 
        summarise(trait = parameter_name[1], x_bar = mean(data_point), x_sd = sd(data_point), 
            n_ind = n()) %>% ungroup() %>% filter(n_ind > min_individuals) %>% 
        # Check both sexes present & filter those missing
    group_by(population) %>% mutate(n_sex = n_distinct(sex)) %>% ungroup() %>% 
        filter(n_sex == 2) %>% select(-n_sex) %>% arrange(production_center, 
        strain_name, population, sex)
}

3) Extraction of effect sizes and sample variances

Function: “create_meta_analysis_effect_sizes”

create_meta_analysis_effect_sizes <- function(mydata) {
    i <- seq(1, nrow(mydata), by = 2)
    input <- data.frame(n1i = mydata$n_ind[i], n2i = mydata$n_ind[i + 1], x1i = mydata$x_bar[i], 
        x2i = mydata$x_bar[i + 1], sd1i = mydata$x_sd[i], sd2i = mydata$x_sd[i + 
            1])
    
    mydata[i, ] %>% select(strain_name, production_center, trait) %>% mutate(effect_size_CVR = calculate_lnCVR(CMean = input$x1i, 
        CSD = input$sd1i, CN = input$n1i, EMean = input$x2i, ESD = input$sd2i, 
        EN = input$n2i), sample_variance_CVR = calculate_var_lnCVR(CMean = input$x1i, 
        CSD = input$sd1i, CN = input$n1i, EMean = input$x2i, ESD = input$sd2i, 
        EN = input$n2i), effect_size_VR = calculate_lnVR(CSD = input$sd1i, CN = input$n1i, 
        ESD = input$sd2i, EN = input$n2i), sample_variance_VR = calculate_var_lnVR(CN = input$n1i, 
        EN = input$n2i), effect_size_RR = calculate_lnRR(CMean = input$x1i, 
        CSD = input$sd1i, CN = input$n1i, EMean = input$x2i, ESD = input$sd2i, 
        EN = input$n2i), sample_variance_RR = calculate_var_lnRR(CMean = input$x1i, 
        CSD = input$sd1i, CN = input$n1i, EMean = input$x2i, ESD = input$sd2i, 
        EN = input$n2i), err = as.factor(seq_len(n())))
}

4) Calculate meta-analysis statistics

Based on a function created by A M Senior @ the University of Otago NZ 03/01/2014:

• Calculates effect sizes for meta-analysis of variance. All functions take the mean, sd and n from the control and experimental groups.
• The first function, calculate_lnCVR, calculates the the log response-ratio of the coefficient of variance (lnCVR) - see Nakagawa et al 2015.
• The second function calculates the measurement error variance for lnCVR. As well as the aforementioned parameters, this function also takes Equal_E_C_Corr (default = T), which must be True or False. If true, the function assumes that the correlation between mean and sd (Taylor’s Law) is equal for the mean and control groups, and, thus these data are pooled. If False the mean-SD correlation for the experimental and control groups are calculated separately from one another.
• Similar functions are then implemented for lnVR (for comparison of standard deviations) and ln RR (for comparison of means)

calculate_lnCVR <- function(CMean, CSD, CN, EMean, ESD, EN) {
    log(ESD) - log(EMean) + 1/(2 * (EN - 1)) - (log(CSD) - log(CMean) + 1/(2 * 
        (CN - 1)))
}

calculate_var_lnCVR <- function(CMean, CSD, CN, EMean, ESD, EN, Equal_E_C_Corr = T) {
    if (Equal_E_C_Corr == T) {
        mvcorr <- 0  # cor.test(log(c(CMean, EMean)), log(c(CSD, ESD)))$estimate   old, slightly incorrect
        S2 <- CSD^2/(CN * (CMean^2)) + 1/(2 * (CN - 1)) - 2 * mvcorr * sqrt((CSD^2/(CN * 
            (CMean^2))) * (1/(2 * (CN - 1)))) + ESD^2/(EN * (EMean^2)) + 1/(2 * 
            (EN - 1)) - 2 * mvcorr * sqrt((ESD^2/(EN * (EMean^2))) * (1/(2 * 
            (EN - 1))))
    } else {
        Cmvcorr <- cor.test(log(CMean), log(CSD))$estimate
        Emvcorr <- cor.test(log(EMean), (ESD))$estimate
        S2 <- CSD^2/(CN * (CMean^2)) + 1/(2 * (CN - 1)) - 2 * Cmvcorr * sqrt((CSD^2/(CN * 
            (CMean^2))) * (1/(2 * (CN - 1)))) + ESD^2/(EN * (EMean^2)) + 1/(2 * 
            (EN - 1)) - 2 * Emvcorr * sqrt((ESD^2/(EN * (EMean^2))) * (1/(2 * 
            (EN - 1))))
    }
    S2
}

calculate_lnVR <- function(CSD, CN, ESD, EN) {
    log(ESD) - log(CSD) + 1/(2 * (EN - 1)) - 1/(2 * (CN - 1))
}

calculate_var_lnVR <- function(CN, EN) {
    1/(2 * (EN - 1)) + 1/(2 * (CN - 1))
}

calculate_lnRR <- function(CMean, CSD, CN, EMean, ESD, EN) {
    log(EMean) - log(CMean)
}

calculate_var_lnRR <- function(CMean, CSD, CN, EMean, ESD, EN) {
    CSD^2/(CN * CMean^2) + ESD^2/(EN * EMean^2)
}

Load & clean data

1) Data loading and cleaning of the csv file

This step we have already done and provide a cleaned up file which is less computing intensive and which we have saved in a folder called export. However, the cvs is provided in case this is preferred to be attempted, following the steps below:

# loads the raw data, setting some default types for various columns

load_raw <- function(filename) {
    read_csv(filename, col_types = cols(.default = col_character(), project_id = col_character(), 
        id = col_character(), parameter_id = col_character(), age_in_days = col_integer(), 
        date_of_experiment = col_datetime(format = ""), weight = col_double(), 
        phenotyping_center_id = col_character(), production_center_id = col_character(), 
        weight_date = col_datetime(format = ""), date_of_birth = col_datetime(format = ""), 
        procedure_id = col_character(), pipeline_id = col_character(), biological_sample_id = col_character(), 
        biological_model_id = col_character(), weight_days_old = col_integer(), 
        datasource_id = col_character(), experiment_id = col_character(), data_point = col_double(), 
        age_in_weeks = col_integer(), `_version_` = col_character()))
}

# Apply some standard cleaning to the data
clean_raw_data <- function(mydata) {
    
    group <- read_csv(here("data", "ParameterGrouping.csv"))
    
    tmp <- mydata %>% 
    # Filter to IMPC source (recommend by Jeremey in email to Susi on 20 Aug
    # 2018)
    filter(datasource_name == "IMPC") %>% 
    # standardise trait names
    mutate(parameter_name = tolower(parameter_name)) %>% 
    # remove extreme ages
    filter(age_in_days > 0 & age_in_days < 500) %>% 
    # remove NAs
    filter(!is.na(data_point)) %>% 
    # subset to reasonable set of variables, date_of_experiment used as an
    # indicator of batch-level effects
    select(production_center, strain_name, strain_accession_id, biological_sample_id, 
        pipeline_stable_id, procedure_group, procedure_name, sex, date_of_experiment, 
        age_in_days, weight, parameter_name, data_point) %>% 
    # sort
    arrange(production_center, biological_sample_id, age_in_days)
    
    # filter to groups with > 1 centre
    merge(tmp, tmp %>% group_by(parameter_name) %>% summarise(center_per_trait = length(unique(production_center, 
        na.rm = TRUE)))) %>% filter(center_per_trait >= 2) %>% 
    # Define population variable
    mutate(population = sprintf("%s-%s", production_center, strain_name)) %>% 
        
    # add grouping variable: these were decided based on functional groups and
    # procedures
    mutate(parameter_group = group$parameter[match(parameter_name, group$parameter_name)]) %>% 
        
    # Assign unique IDs (per trait) each unique parameter_name (=trait,use trait
    # variable) gets a unique number ('id')
    
    # We add a new variable, where redundant traits are combined [note however,
    # at this stage the dataset still contains nonsensical traits, i.e. traits
    # that may not contain any information on variance]
    mutate(id = match(parameter_name, unique(parameter_name))) %>% as_tibble()
}

# Load raw data - save cleaned dataset as RDS for reuse
data_raw <- load_raw(here("data", "dr7.0_all_control_data.csv.gz"))
dir.create("export", F, F)

data <- data_raw %>% clean_raw_data()
saveRDS(data, "export/data_clean.rds")

For analysis we load the RDS created above and other datasets:

data <- readRDS(here("export", "data_clean.rds"))

procedures <- read_csv(here("data", "procedures.csv"))

Checking length of different variables and sample sizes.

Loop: Meta-analyses on all traits

• The loop combines the functions mentioned above and fills the data matrix with results from our meta analysis.
• Error messages indicate traits that either did not reach convergence, or that did not return meaningful results in the meta-analysis, due to absence of variance. Those traits will be removed in later steps, outlined below.

In the above function, we use ‘tryCatch’ and ‘conditionMessage’ to prevent the loop from aborting when the first error at row 84 is produced. As convergence in the two listed non-converging cases can’t be achieved by sensibly tweaking (other optim etc.), and we only learn about non-convergence in the loop, it is not possible to exclude the traits (N=2) beforehand. Similarly, there are 8 traits with very low variation, which can not be excluded prior to running the loop.

The produced “Warnings” indicate cases where variance components are set to zero during likelihood optimization.

Merging datasets & removal of non-converged traits

Procedure names, grouping variables and trait names (“parameter_names”) are merged back together with the results from the metafor analysis above.

results_alltraits_grouping2 <- 
  results_alltraits_grouping %>% 
  left_join(by="id",
             data %>% select(id, parameter_group, procedure = procedure_name, procedure_name, parameter_name) %>%   # We filter duplicated id's to get only one unique row per id (and there is one id per parameter_name)
              filter(!duplicated(id))
            ) %>%
  # Below we add 'procedure' (from the previously loaded 'procedures.csv') as a variable
  left_join(by="procedure", 
            procedures %>% distinct()
            )

#(n <- length(unique(results_alltraits_grouping2$parameter_name))) # 232

Removal of traits

14 traits from the originally 232 that had been included are removed because they either did not achieve convergence or are nonsensical for analysis of variance (such as traits that show no variation, see list below).

Not converged: “dp t cells”, “mzb (cd21/35 high)”

Not enough variation: “number of caudal vertebrae”, “number of cervical vertebrae”, “number of digits”, “number of lumbar vertebrae”, “number of pelvic vertebrae”, “number of ribs left”,“number of ribs right”, “number of signals”, “number of thoracic vertebrae”, “total number of acquired events in panel a”,“total number of acquired events in panel b”, “whole arena permanence”.

# We exclude 14 parameter names for which metafor models didn't converge
# ('dp t cells', 'mzb (cd21/35 high)'), and of parameters that don't harbour
# enough variation
meta_clean <- results_alltraits_grouping2 %>% filter(!parameter_name %in% c("dp t cells", 
    "mzb (cd21/35 high)", "number of caudal vertebrae", "number of cervical vertebrae", 
    "number of digits", "number of lumbar vertebrae", "number of pelvic vertebrae", 
    "number of ribs left", "number of ribs right", "number of signals", "number of thoracic vertebrae", 
    "total number of acquired events in panel a", "total number of acquired events in panel b", 
    "whole arena permanence"))

2. Meta-analysis: condensing non-independent traits

(Step F in Figure 3 in main article)

Dealing with Correlated Parameters, preparation

This dataset contained a number of highly correlated traits, such as different kinds of cell counts (for example hierarchical parameterization within immunological assays). As those data-points are not independent of each other, we conducted meta analyses on these correlated parameters to collapse the number of levels.

Collapsing and merging correlated parameters

Here we double check numbers of trait parameters in the dataset

meta1 <- meta_clean
length(unique(meta1$procedure))  #18

## [1] 18

length(unique(meta1$GroupingTerm))  #9

## [1] 9

length(unique(meta1$parameter_group))  # 148 levels. To be used as grouping factor for meta-meta-analysis / collapsing down based on things that are classified identically in 'parameter_group' but have different 'parameter_name'

## [1] 148

length(unique(meta1$parameter_name))  #218

## [1] 218

Count of number of parameter names (correlated sub-traits) in each parameter group (par_group_size)

Table 2: Numbers of correlated and uncorrelated traits

This serves to identify and separate the traits that are correlated from the full dataset that can be processed as is. If the sample size (n) for a given “parameter group” equals 1, the trait is unique and uncorrelated. All instances, where there are 2 or more traits associated with the same parameter group (90 cases), are selected for a “mini-meta analysis”, which removes the issue of correlation.

Meta-analyses on correlated (sub-)traits, using robumeta`

# merge back together

meta1b <- meta1 %>% group_by(parameter_group) %>% summarize(par_group_size = length(unique(parameter_name,

Extracting and save parameter estimates

Here we apply an additional Function to collect the outcomes of the ‘mini-meta-analysis’ that has ondensed our non-independent traits.

count_fun <- function(mod_sub) {
    return(c(mod_sub$reg_table$b.r, mod_sub$reg_table$CI.L, mod_sub$reg_table$CI.U, 
        mod_sub$reg_table$SE))
}  # estimate, lower ci, upper ci, SE

Extraction of values created during meta-analyses using robumeta

robu_all <- full_join(robusub_CVR, robusub_VR) %>% full_join(., robusub_RR)

Combining data

Merge the two data sets (the new [robu_all] and the initial [uncorrelated sub-traits with count = 1])

meta_all <- meta1 %>% filter(par_group_size == 1) %>% as_tibble()
# glimpse(meta_all) glimpse(robu_all)

# Step 1: Columns are matched by name (in our case, 'parameter_group'), and
# any missing columns will be filled with NA
combinedmeta <- bind_rows(robu_all, meta_all)
# glimpse(combinedmeta)

# Steps 2&3: Add information about number of traits in a parameter group,
# procedure, and grouping term

Table 3: Full corrected dataset

We use this corrected (for correlated traits) “results” table, which contains each of the meta-analytic means for all effect sizes of interest, for further analyses. We further use this table as part of the Shiny App, which is able to provide the percentage differences between males and females for mean, variance and coefficient of variance.

This is the full result dataset

3. Second-order meta-analysis for functional groups

(Section H in Figure 3 in main article)

Performing meta-analyses (3 for each of the 9 grouping terms: lnCVR, lnVR, lnRR)

Preparation of data

Nesting, calculating the number of parameters within each grouping term, and running the meta-analyses

metacombo_final <- metacombo %>% group_by(GroupingTerm) %>% nest()

# **calculate number of parameters per grouping term

metacombo_final <- metacombo_final %>% mutate(para_per_GroupingTerm = map_dbl(data, 
    nrow))

# For all grouping terms
metacombo_final_all <- metacombo %>% nest(data = everything())


# **Final fixed effects meta-analyses within grouping terms, with SE of the
# estimate

overall1 <- metacombo_final %>% 
mutate(model_lnCVR = map(data, ~metafor::rma.uni(yi = .x$lnCVR, sei = (.x$lnCVR_upper - 
    .x$lnCVR_lower)/(2 * 1.96), control = list(optimizer = "optim", optmethod = "Nelder-Mead", 
    maxit = 1000), verbose = F)), model_lnVR = map(data, ~metafor::rma.uni(yi = .x$lnVR, 
    sei = (.x$lnVR_upper - .x$lnVR_lower)/(2 * 1.96), control = list(optimizer = "optim", 
        optmethod = "Nelder-Mead", maxit = 1000), verbose = F)), model_lnRR = map(data, 
    ~metafor::rma.uni(yi = .x$lnRR, sei = (.x$lnRR_upper - .x$lnRR_lower)/(2 * 
        1.96), control = list(optimizer = "optim", optmethod = "Nelder-Mead", 
        maxit = 1000), verbose = F)))

# **Final fixed effects meta-analyses ACROSS grouping terms, with SE of the
# estimate

overall_all1 <- metacombo_final_all %>% 
mutate(model_lnCVR = map(data, ~metafor::rma.uni(yi = .x$lnCVR, sei = (.x$lnCVR_upper - 
    .x$lnCVR_lower)/(2 * 1.96), control = list(optimizer = "optim", optmethod = "Nelder-Mead", 
    maxit = 1000), verbose = F)), model_lnVR = map(data, ~metafor::rma.uni(yi = .x$lnVR, 
    sei = (.x$lnVR_upper - .x$lnVR_lower)/(2 * 1.96), control = list(optimizer = "optim", 
        optmethod = "Nelder-Mead", maxit = 1000), verbose = F)), model_lnRR = map(data,

        1.96), control = list(optimizer = "optim", optmethod = "Nelder-Mead", 
        maxit = 1000), verbose = F)))

Re-structuring the data for each grouping term

We here delete unused variables, and select the respective effect sizes. Please note - the referencing of the cells does NOT depend on previous ordering of the data. This would only be affected if the output structure from metafor::rma.uni changes.

Figure 4

Panel A shows the numbers of traits across functional groups that are either male-biased (blue-green) or female-biased (orange-red), as calculated in Step D (figure 3). Panel B shows effect sizes and 95% CI from separate meta-analysis for each functional group (step H in Figure 3). Both panels represent results evaluated across all traits (Phase 3, Figure 3). Traits that are male biased is shown in blue, whereas female bias data is represented in orange.

Preparing data for traits with CI not overlapping 0

To further investigate sex bias in this dataset, and in particular if the extent of sex bias differs between traits, we investigate the magnitude of male- and female bias in significantly different traits on (both for means and variability)

To do this, we select only traits that have CIs that do not overlap with zero. The code below creates Figure 5A.
