Question about creating the COHORT table in CDM




I wanted to ask if it is possible to create cohort using either the CohortMethod R package or ATLAS such that the subject_id field in the COHORT table refers to a record in the VISIT_OCCURRENCE table?

Thank you in advance!

For Atlas, the tools are person-centric, so it doesn’t function that way (a visit_id in the subject_id field)


Thank you for letting me know!
