Create a parameter object for the function createStudyPopulation

removeDuplicateSubjects = "keep all",
removeSubjectsWithPriorOutcome = TRUE,

)
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? |
Create an object defining the parameter values.
