Introduction

In this example we’re going to summarise cohort diagnostics results for cohorts of individuals with an ankle sprain, ankle fracture, forearm fracture, or a hip fracture using the Eunomia synthetic data.

Again, we’ll begin by creating our study cohorts.

library(CDMConnector)
library(CohortConstructor)
library(CodelistGenerator)
library(PatientProfiles)
library(CohortCharacteristics)
library(phenotypeR)
library(dplyr)
library(ggplot2)

con <- DBI::dbConnect(duckdb::duckdb(),
  dbdir = CDMConnector::eunomia_dir()
)
cdm <- CDMConnector::cdm_from_con(con,
  cdm_schem = "main",
  write_schema = "main",
  cdm_name = "Eunomia"
)

cdm$injuries <- conceptCohort(cdm = cdm,
  conceptSet = list(
    "ankle_sprain" = 81151,
    "ankle_fracture" = 4059173,
    "forearm_fracture" = 4278672,
    "hip_fracture" = 4230399
  ),
  name = "injuries")

Cohort diagnostics

We can run cohort diagnostics analyses for each of our overall cohorts like so:

cohort_diag <- cohortDiagnostics(cdm$injuries)

Our results will include a summary of the overlap between our cohorts. We could visualise this

plotCohortOverlap(cohort_diag, uniqueCombinations = TRUE)

Moreover, our results will also include a summary of the characteristics of each cohort

Cohort diagnostics - stratified by age and sex

Say we wanted the same analyses to be performed, but stratified by age and sex. We can do this by first adding these characteristics to our cohort table.

cdm$injuries <- cdm$injuries |> 
  addDemographics(ageGroup = list(c(0, 17),
                                  c(18, 65),
                                  c(66, Inf))) |> 
  compute(name = "injuries") |> 
  omopgenerics::newCohortTable()

cdm$injuries |> 
  dplyr::glimpse()

Now we can include these additional variables for stratification when running our analyses.

cohort_diag <- cohortDiagnostics(cdm$injuries, strata = c("sex", "age_group"))

Again we can visualise our results, but this time we have both stratified and overall results.

plotCohortOverlap(cohort_diag, uniqueCombinations = TRUE, facet = c("age_group", "sex"))
