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

createRestrictPlpDataSettings define extra restriction settings when calling getPlpData

Description

This function creates the settings used to restrict the target cohort when calling getPlpData

Usage

createRestrictPlpDataSettings(
  studyStartDate = "",
  studyEndDate = "",
  firstExposureOnly = F,
  washoutPeriod = 0,
  sampleSize = NULL
)

Arguments

studyStartDate	A calendar date specifying the minimum date that a cohort index date can appear. Date format is 'yyyymmdd'.
studyEndDate	A calendar date specifying the maximum date that a cohort index date can appear. Date format is 'yyyymmdd'. Important: the study end data is also used to truncate risk windows, meaning no outcomes beyond the study end date will be considered.
firstExposureOnly	Should only the first exposure per subject be included? Note that this is typically done in the createStudyPopulation function, but can already be done here for efficiency reasons.
washoutPeriod	The mininum required continuous observation time prior to index date for a person to be included in the at risk cohort. Note that this is typically done in the createStudyPopulation function, but can already be done here for efficiency reasons.
sampleSize	If not NULL, the number of people to sample from the target cohort

Details

Users need to specify the extra restrictions to apply when downloading the target cohort

Value

A setting object of class restrictPlpDataSettings containing a list getPlpData extra settings
