Filter to Include Lab Tests
The Filter to Include Lab Tests field is an optional parameter that enables you to subset rows from the LB.sas7bdat data set for analysis. Only those subjects that meet all of the conditions specified in the field are included in the analysis.
For example, to include only results from ALT tests (as indicated in the LBTESTCD column), you could use the following simple WHERE expression:
WHERE LBTESTCD = ‘ALT’
Note: the word where has already been entered for you.
For more information about using filter fields, see The SAS WHERE Expression.
