Extracts covariates from Observational Medical
Outcomes Partnership (OMOP) Common Data Model (CDM) domains using an
R-only pipeline. Supports configurable temporal windows,
domain-specific covariates for drug exposure, drug era (including
Anatomical Therapeutic Chemical (ATC) groupings), condition
occurrence, condition era, concept sets and cohorts. Methods are
based on the Observational Health Data Sciences and Informatics
(OHDSI) framework described in Hripcsak et al. (2015)
