}
```
3) Meta Analysis
Function to calculate meta-analysis statistics. Created by A M Senior @ the University of Otago NZ 03/01/2014
Below are functions for calculating effect sizes for meta-analysis of variance.
All functions take the mean, sd and n from the control and experimental groups.
The first function, Cal.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)
```{r}
Calc.lnCVR <- function(CMean, CSD, CN, EMean, ESD, EN){
log(ESD) - log(EMean) + 1 / (2*(EN - 1)) - (log(CSD) - log(CMean) + 1 / (2*(CN - 1)))
}
Calc.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
}
Calc.lnVR <- function(CSD, CN, ESD, EN){
log(ESD) - log(CSD) + 1 / (2*(EN - 1)) - 1 / (2*(CN - 1))
}
Calc.var.lnVR <- function( CN, EN) {
1 / (2*(EN - 1)) + 1 / (2*(CN - 1))
}
Calc.lnRR <- function(CMean, CSD, CN, EMean, ESD, EN) {
log(EMean) - log(CMean)
}
Calc.var.lnRR <- function(CMean, CSD, CN, EMean, ESD, EN) {
CSD^2/(CN * CMean^2) + ESD^2/(EN * EMean^2)
}
```
## The dataset
Having loaded the necessary functions, we can get started on the dataset.
We here provide the cleaned dataset, which we have saved in a folder called "export", as easy starting point. However, the full dataset can be loaded and cleaned using the data cleaning function (Function 1 above), if "#" signs in the code below are removed (created as that is much smaller than the .csv - which we can still provide for those who absolutely want to start from scratch?)
#### Preparation of raw 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. However, the cvs is provided in case this is pereferred to be attempted, following the steps below:
```{r Raw Data, eval=FALSE, include=TRUE}
# 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) {
mydata %>%
# Fileter to IMPC source (recommened 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: Jeremy suggested using 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) %>%
arrange(production_center, biological_sample_id, age_in_days)
}
```
2) Subsetting the data to choose only one data point per individual per trait
```{r}
#2) Subsetting the data to choose only one data point per individual per trait
# this is a necessary step for the loop across all traits
data_subset_parameterid_individual_by_age <- function(mydata, parameter, age_min, age_center) {
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)
# still some individuals with multiple records (because same individual appears under different procedures, so filter to one record)
j <- match(unique(tmp$biological_sample_id), tmp$biological_sample_id)
tmp[j, ]
}
```
### Load data (raw / pre-clean)
```{r}
## Load raw data - save cleaned dataset as RDS for reuse
#data_raw <- load_raw("data/dr7.0_all_control_data.csv") %>%
# clean_raw_data()
#dir.create("export", F, F)
#saveRDS(data_raw, "export/data_clean.rds")
getwd()
data1 <- readRDS("export/data_clean.rds")
#data1
```
### Clean data
This requires the selection of traits that have been measured in at least 2 centers. Consequently, rare or unusual methods and procedures are being filtered out in this step.
```{r }
dat1 <-
data1 %>%
group_by(parameter_name) %>%
summarize(center_per_trait = length(unique(production_center, na.rm = TRUE)))
dat2 <- merge(data1, dat1)
dat_moreThan1center <-
dat2 %>%
filter(center_per_trait >= 2)
data2 <- dat_moreThan1center
#min(data2$center_per_trait) # as a check if there indeed are no single occurences
```
## Meta analysis, Phase 1: across all traits
### Preparation
####Define population variable
& add grouping variables
In this step, a grouping variable is added (found in "Parameter.Grouping.csv")
The grouping variables were decided based on functional groups and procedures
```{r }
data3 <- data2 %>%
mutate(population = sprintf("%s-%s", production_center, strain_name))
group <- read.csv("export/ParameterGrouping.csv")
data <- data3
data$parameterGroup <- group$parameter[match(data$parameter_name, group$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]
```{r}
#head(data)
names(data)[16] <- "parameter_group"
data <- transform(data, id = match(parameter_name, unique(parameter_name)))
n1 <- length(unique(data$parameter_name)) #232
n2 <- length(unique(data$parameter_group)) #161
n3 <- length(unique(data$procedure_name)) # 26
n <- length(unique(data$id))
#n # just to check that the number of traits is 232
```
#### Create matrix
As the current version of this script utilizes a loop instead of tidyR code, it is here necessary to create an empty matrix, in which the returning values will be stored.
```{r}
results.alltraits.grouping <- as.data.frame(cbind(c(1:n), matrix(rep(0, n*14), ncol = 14))) #number of individual results per trait = 10
names(results.alltraits.grouping) <- c("id", "lnCVR", "lnCVR_lower", "lnCVR_upper", "lnCVR_se", "lnVR", "lnVR_lower", "lnVR_upper", "lnVR_se", "lnRR", "lnRR_lower", "lnRR_upper" ,"lnRR_se" , "sampleSize", "trait")
```
#### Loop running meta-analysis 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.
```{r}
for(t in 1:n) {
tryCatch({
data_par_age <- data_subset_parameterid_individual_by_age(data, t, age_min = 0, age_center = 100)
population_stats <- calculate_population_stats(data_par_age)
results <- create_meta_analysis_effect_sizes(population_stats)
#lnCVR, log repsonse-ratio of the coefficient of variance
cvr <- metafor::rma.mv(yi = effect_size_CVR, V = sample_variance_CVR, random = list(~1| strain_name, ~1|production_center, ~1|err), control=list(optimizer="optim", optmethod="Nelder-Mead", maxit= 1000), verbose=F, data = results)
results.alltraits.grouping[t, 2] <- cvr$b
results.alltraits.grouping[t, 3] <- cvr$ci.lb
results.alltraits.grouping[t, 4] <- cvr$ci.ub
results.alltraits.grouping[t, 5] <- cvr$se
cvr
#lnVR, comparison of standard deviations
cv <- metafor::rma.mv(yi = effect_size_VR, V = sample_variance_VR, random = list(~1| strain_name, ~1|production_center,~1|err), control=list(optimizer="optim", optmethod="Nelder-Mead", maxit= 1000), verbose=F, data = results)
results.alltraits.grouping[t, 6] <- cv$b
results.alltraits.grouping[t, 7] <- cv$ci.lb
results.alltraits.grouping[t, 8] <- cv$ci.ub
results.alltraits.grouping[t, 9] <- cv$se
# for means, lnRR
means <- metafor::rma.mv(yi = effect_size_RR, V = sample_variance_RR, random = list(~1| strain_name, ~1|production_center, ~1|err), control=list(optimizer="optim", optmethod="Nelder-Mead", maxit= 1000), data = results)
results.alltraits.grouping[t, 10] <- means$b
results.alltraits.grouping[t, 11] <- means$ci.lb
results.alltraits.grouping[t, 12] <- means$ci.ub
results.alltraits.grouping[t, 13] <- means$se
results.alltraits.grouping[t, 14] <- means$k
results.alltraits.grouping[t, 15] <- unique(results$trait)
}, error=function(e){cat("ERROR :",conditionMessage(e), "\n")})
}
# Now that we have a "results" table with each of the meta-analytic means for all effect sizes of interest, we can use this table as part of the Shiny App, which will then be able to back calculate the percentage differences between males and females for mean, variance and coefficient of variance. We'll export and use this in the Shiny App. **Note that I have not dealt with convergence issues in some of these models, and so, this will need to be done down the road**
## Note Susi 31/7/2019: This dataset contains dublicated values, plus no info on what the "traits" mean. I will change Dan N's to one further belwo, that have been cleaned up already
#FILE TO USE: METACOMBO (around line 500)
#trait_meta_results <- write.csv(results.alltraits.grouping, file = "export/trait_meta_results.csv")
```
#### Merging datasets & removal of non-converged traits
Procedure names, grouping variables etc. are merged back together with the results from the metafor analysis above.
This requires loading of another excel sheet, "procedures.csv"
```{r}
procedures <- read.csv("export/procedures.csv")
results.alltraits.grouping$parameter_group <- data$parameter_group[match(results.alltraits.grouping$id, data$id)]
results.alltraits.grouping$procedure <- data$procedure_name[match(results.alltraits.grouping$id, data$id)]
results.alltraits.grouping$GroupingTerm <- procedures$GroupingTerm[match(results.alltraits.grouping$procedure, procedures$procedure)]
results.alltraits.grouping$parameter_name <- data$parameter_name[match(results.alltraits.grouping$id, data$id)]
meta1 <- results.alltraits.grouping
n <- length(unique(meta1$parameter_name)) # 232
```
Removal of traits that did not achieve convergence, are nonsensical for analysis of variance (such as traits that show variation, such as number of ribs, digits, etc). 14 traits from the originally 232 that had been included are removed.
```{r}
meta_clean <- meta1[ !(meta1$id %in% c(84,144,158,160,161,162,163,165,166,167,168,221,222,231)), ]
removed <-length(unique(meta_clean$parameter_name)) #218
```
## Meta-analysis, Phase 2: non-independent traits
### Dealing with Correlated Parameters, preparation
This dataset contained a number of highly correlated traits, such as different kinds of cell counts (for example, hierarchical parameterization within immunological assays). As those data-points are not independent of each other, we conducted a meta analyses on these correlated parameters to collapse the number of levels.
#### Collapsing and merging correlated parameters
Here we double check numbers of trait parameters in the dataset
```{r}
meta1 <- meta_clean
# length(unique(meta1$procedure)) #18
# length(unique(meta1$GroupingTerm)) #9
# length(unique(meta1$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"
#length(unique(meta1$parameter_name)) #218
```
#### Count of number of parameter names (correlated sub-traits) in each parameter group (par_group_size)
This serves to identify and separate the traits that are correlated from the full dataset that can be processed as is. If the sample size (n) for a given "parameter group" equals 1, the trait is unique and uncorrelated. All instances, where there are 2 or more traits associated with the same parameter group (90 cases), are selected for a "mini-meta analysis", which removes the issue of correlation.
```{r}
kable(cbind (meta1 %>% count(parameter_group) )) %>%
kable_styling() %>%
scroll_box(width = "100%", height = "200px")
meta1b <-
meta1 %>%
group_by(parameter_group) %>%
summarize(par_group_size = length(unique(parameter_name, na.rm = TRUE)))
#this gives a summary of number of parameter names in each parameter group, now it neeeds to get merged it back together
meta1$par_group_size <- meta1b$par_group_size[match(meta1$parameter_group, meta1b$parameter_group)]
# Create subsets with > 1 count (par_group_size > 1)
meta1_sub<-subset(meta1,par_group_size >1) # 90 observations
meta1_sub$sampleSize <- as.numeric(meta1_sub$sampleSize)
```
#### Meta-analyses on correlated (sub-)traits, using robumeta`
The subset of the data is prepared (nested), and in this first step the model of the meta analysis effect sizes are calculated
```{r}
# nesting
n_count <- meta1_sub %>%
group_by(parameter_group) %>%
mutate(raw_N = sum(sampleSize)) %>%
nest()
model_count <- n_count %>%
mutate(model_lnRR = map(data, ~ robu(.x$lnRR ~ 1, data= .x, studynum= .x$id, modelweights = c("CORR"), rho = 0.8, small = TRUE, var.eff.size= (.x$lnRR_se)^2 )),
model_lnVR = map(data, ~ robu(.x$lnVR ~ 1, data= .x, studynum= .x$id, modelweights = c("CORR"), rho = 0.8, small = TRUE, var.eff.size= (.x$lnVR_se)^2 )),
model_lnCVR = map(data, ~ robu(.x$lnCVR ~ 1, data= .x, studynum= .x$id, modelweights = c("CORR"), rho = 0.8, small = TRUE, var.eff.size= (.x$lnCVR_se)^2 )))
```
Extract and save parameter estimates:
Function to collect the outcomes of the "mini" meta analysis
```{r}
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 analysis using robu meta:
```{r}
robusub_RR <- model_count %>%
transmute(parameter_group, estimatelnRR = map(model_lnRR, count_fun)) %>%
mutate(r = map(estimatelnRR, ~ data.frame(t(.)))) %>%
unnest(r) %>%
select(-estimatelnRR) %>%
purrr::set_names(c("parameter_group","lnRR","lnRR_lower","lnRR_upper","lnRR_se"))
robusub_CVR <- model_count %>%
transmute(parameter_group, estimatelnCVR = map(model_lnCVR, count_fun)) %>%
mutate(r = map(estimatelnCVR, ~ data.frame(t(.)))) %>%
unnest(r) %>%
select(-estimatelnCVR) %>%
purrr::set_names(c("parameter_group","lnCVR","lnCVR_lower","lnCVR_upper","lnCVR_se"))
robusub_VR <- model_count %>%
transmute(parameter_group, estimatelnVR = map(model_lnVR, count_fun)) %>%
mutate(r = map(estimatelnVR, ~ data.frame(t(.)))) %>%
unnest(r) %>%
select(-estimatelnVR) %>%
purrr::set_names(c("parameter_group","lnVR","lnVR_lower","lnVR_upper","lnVR_se"))
robu_all <- full_join(robusub_CVR, robusub_VR) %>% full_join(., robusub_RR)
kable(cbind(robu_all, robu_all)) %>%
kable_styling() %>%
scroll_box(width = "100%", height = "200px")
```
Merge the two data sets (the new [robu_all] and the initial [uncorrelated sub-traits with count = 1])
```{r}
meta_all <- meta1 %>% filter(par_group_size == 1) %>% as_tibble
#str(meta_all)
#str(robu_all)
#which(is.na(match(names(meta_all),names(robu_all)))) # check
```
#### Combine data
```{r}
# Step1
combinedmeta <- bind_rows(robu_all, meta_all)
#glimpse(combinedmeta)
# Steps 2&3
metacombo <- combinedmeta
metacombo$counts <- meta1$par_group_size[match( metacombo$parameter_group, meta1$parameter_group)]
metacombo$procedure2 <-meta1$procedure[match( metacombo$parameter_group, meta1$parameter_group)]
metacombo$GroupingTerm2 <-meta1$GroupingTerm[match( metacombo$parameter_group, meta1$parameter_group)]
kable(cbind (metacombo, metacombo)) %>%
kable_styling() %>%
scroll_box(width = "100%", height = "200px")
```
Clean-up and rename
```{r}
metacombo <-metacombo[, c(1, 21:23, 2:13)]
names(metacombo)[3] <- "procedure"
names(metacombo)[4] <- "GroupingTerm"
# Quick pre-check before doing plots
compare <- metacombo %>%
group_by(GroupingTerm) %>%
dplyr::summarize(MeanCVR = mean(lnCVR),MeanVR = mean(lnVR), MeanRR = mean(lnRR) )
compare
```
```{r}

## Meta-analysis, Phase 3: Second-order meta analysis for functional groups
#### Perform meta-analyses (3 for each of the 9 grouping terms: lnCVR, lnVR, lnRR)
This is the full result dataset
```{r}
kable(cbind (metacombo,metacombo)) %>%
kable_styling() %>%
scroll_box(width = "100%", height = "200px")
```
#### Prepare data
Nesting, calculating the number of parameters within each grouping term, and running the meta-analysis
