# Filter to Choose Disposition Event for Completion or Discontinuation Status

The Filter to Choose Disposition Event for Completion or Discontinuation Status field is an optional parameter that enables you to filter rows from the DS data set to choose the appropriate records to indicate final trial status (COMPLETED or WITHDRAWN/DISCONTINUED, for example). Only those rows that meet all of the conditions specified in the field are included in the analysis.

There should be one record per person. If multiple records are present for a subject, this report will choose the last. If no text is specified, the latest record where DSCAT = "DISPOSITION EVENT" from the TREATMENT epoch is used.

Note: It is necessary to use quotation marks when filtering data using values of a character variable (DSCAT = "DISPOSITION EVENT", for example), but no quotation marks are required for filtering by values of a numeric variable.

You can enter one or more statements (joined by AND or OR) in this field.

The syntax of this filter expression follows the syntax of SAS WHERE statements. For more information about this syntax, see The SAS WHERE Expression.
