# Filter to Choose Adverse Events for RBM

The Filter to Choose Adverse Events for RBM Status field is an optional parameter that enables you to filter rows from the AE data set to choose the appropriate records to subset to adverse events of interest. Risk indicators are calculated using this subset of adverse events only.

Note: It is necessary to use quotation marks when filtering data using values of a character variable (AEBODSYS = "VASCULAR DISORDERS", 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.
