Count multiple occurrences of an event per subject
Select the method by which to compute counts of adverse events.
Each subject contributes only one time to the occurrence count of an event, regardless of how many times that specific event might have occurred to the subject.
Note: This option sorts the data so that the first event occurring to a subject is based on seriousness (AESER), severity (AESEV or AETOXGR), and Study day (AESTDY).
