-
A coded value specifying when this adverse event ended with respect to the sponsor-defined reference period. EXAMPLE(S): before, during, during/after, after. NOTE(S): if the reference period is computably represented, AdverseEvent.endRelativeToReferenceCode is conceptually derivable based on the reference period and the resolution date of the adverse event. Sponsors should define the reference period in the study metadata. This may be populated when a start date is not.
