Filter the data
with a single key
Click any cell and press D to filter the dataset to rows matching that value. Chain conditions, undo steps with Z, or apply the same WHERE clause across the entire library with L.
Filter the data
Frequency tables
in one right-click
Right-click any column and choose Frequency — or press F. Hold Ctrl and click multiple columns for a crosstab. Press N to count distinct USUBJIDs per value — indispensable for safety reviews.
Library filter —
one WHERE across all domains
Right-click a value and choose a WHERE clause: StatDataViewer applies it to every dataset in the library at once. Open ADAE, ADLB, and ADCM simultaneously — all filtered to the same subject. Perfect for subject-level data review.
