createCohortCovariateSettings: Extracts covariates based on cohorts

In OHDSI/PatientLevelPrediction: Developing patient level prediction using data in the OMOP Common Data Model

Extracts covariates based on cohorts

Description

Extracts covariates based on cohorts

Usage

createCohortCovariateSettings(
  cohortName,
  settingId,
  cohortDatabaseSchema,
  cohortTable,
  cohortId,
  startDay = -30,
  endDay = 0,
  count = F,
  ageInteraction = F,
  lnAgeInteraction = F,
  analysisId = 456
)

Arguments

cohortName	Name for the cohort
settingId	A unique id for the covariate time and
cohortDatabaseSchema	The schema of the database with the cohort
cohortTable	the table name that contains the covariate cohort
cohortId	cohort id for the covariate cohort
startDay	The number of days prior to index to start observing the cohort
endDay	The number of days prior to index to stop observing the cohort
count	If FALSE the covariate value is binary (1 means cohort occurred between index+startDay and index+endDay, 0 means it did not) If TRUE then the covariate value is the number of unique cohort_start_dates between index+startDay and index+endDay
ageInteraction	If TRUE multiple covariate value by the patient's age in years
lnAgeInteraction	If TRUE multiple covariate value by the log of the patient's age in years
analysisId	The analysisId for the covariate

Details

The user specifies a cohort and time period and then a covariate is constructed whether they are in the cohort during the time periods relative to target population cohort index

Value

An object of class covariateSettings specifying how to create the cohort covariate with the covariateId cohortId x 100000 + settingId x 1000 + analysisId
