Create a parameter object for the function createStudyPopulation

createCreateStudyPopulationArgs(
  firstExposureOnly = FALSE,
  restrictToCommonPeriod = FALSE,
  washoutPeriod = 0,
  removeDuplicateSubjects = "keep all",
  removeSubjectsWithPriorOutcome = TRUE,
  priorOutcomeLookback = 99999,

Arguments

firstExposureOnly: Should only the first exposure per subject be included?
restrictToCommonPeriod: Restrict the analysis to the period when both exposures are observed?
washoutPeriod: The minimum required continuous observation time prior to index date for a person to be included in the cohort.
removeDuplicateSubjects: Remove subjects that are in both the target and comparator cohort? See details for allowed values.
removeSubjectsWithPriorOutcome: Remove subjects that have the outcome prior to the risk window start?
priorOutcomeLookback: How many days should we look back when identifying prior outcomes?
minDaysAtRisk: The minimum required number of days at risk. Risk windows with fewer days than this number are removed from the analysis.
maxDaysAtRisk: The maximum allowed number of days at risk. Risk windows that are longer will be truncated to this number of days.
riskWindowStart: The start of the risk window (in days) relative to the startAnchor.
startAnchor: The anchor point for the start of the risk window. Can be "cohort start" or "cohort end".
riskWindowEnd: The end of the risk window (in days) relative to the endAnchor.
endAnchor: The anchor point for the end of the risk window. Can be "cohort start" or "cohort end".
censorAtNewRiskWindow: If a subject is in multiple cohorts, should time-at-risk be censored when the new time-at-risk starts to prevent overlap?
