Clinical data for a study event (visit). The model supports repeating study events (for example, when the same set of information is collected for a series of patient visits).
The StudyEventOID and StudyEventRepeatKey are used together to identify a particular study event. This pair of values uniquely identifies a StudyEvent within the containing subject. The StudyEventRepeatKey is present if and only if the StudyEventDef is repeating.
