DEFINITION :  The Related Records (RELREC) domain establishes links between records from different SDTM domains. It allows the study team to associate data from multiple domains when they are related, such as linking an adverse event with a corresponding laboratory test.

PURPOSE : To create connections between data points across domains. This is particularly useful in studies where events or findings are closely related and need to be interpreted together.

STRUCTURE : One record per related record, group of records or datasets

TOPIC : NA

KEY VARIABLES : STUDYID, RDOMAIN, USUBJID, IDVAR, IDVARVAL, RELID
