LD Prevalence Selection Tab

In a Limited-Duration Prevalence session, the selection statements on the Selection tab define for SEER*Stat the subset of cases you wish to use in your analysis. There are three selection boxes on the Selection tab:

Each box contains a separate set of variables. No variable is repeated among the boxes. When making selections, start at the top and work your way down the window. If the name of a box has changed to "Not Applicableā€, then no variables exist for this box and the Edit button associated with the box is disabled.

To begin building a selection statement, click the Edit button next to the appropriate text box. If there are no selection statements, all cases in the database will be selected. Therefore, you should only make selection statements for variables used to exclude cases. To clear all statements from a selection box, click Clear.

Multiple Primary Selection

The Multiple Primary Selections option provides several methods for selecting the specific tumor or tumors of interest for an individual. Choose a Multiple Primary Selection option from the drop-down list at the bottom of the Selection tab.

Exclude all Death Certificate and Autopsy Cases Only

Records with a diagnosis based only on death certificate or autopsy are always excluded in Limited-Duration Prevalence sessions. Therefore, this box is always checked and cannot be changed.  It is displayed on the dialog for informational purposes only.
