Details

This function defines the baseline and treatment period columns from clinical data from electronic health record (EHR) databases that have adopted the Observational Medical Outcomes Partnership (OMOP) Common Data Model (CDM) format.

Baseline period = "start_date" to "first_drug_exposure". Treatment period = ("first_drug_exposure" + 30 days) to "last_drug_exposure". If treatment period > 12 months, then treatment period = ("first_drug_exposure" + 30 days) to "end_date".
