The document discusses the SDTM 3.1.2 Findings About (FA) domain. FA is used to store findings that do not fit in other domains or supplemental qualifiers. It provides examples of when to use FA, such as to store adverse event severity timings or details of a prerequisite condition not in the Medical History domain. The document also discusses how to relate unrelated FA data to the parent domain using multiple datasets linked with RELREC relationships. Important FA variables include FATEST/FATESTCD to describe measurements/events and FAOBJ to describe the event/intervention measured.
