Additional Filter to include Adverse Events Use this option to filter rows from the DS data set to choose the appropriate records to indicate final trial status (e.g., COMPLETED or WITHDRAWN/DISCONTINUED). There should be one record per person, but the report will choose the last if multiple records are present per person. If no text is specified, the last record where DSCAT = "DISPOSITION EVENT" is used. For more information about using filter fields, see The SAS WHERE Expression.
