Rate Selection Tab

The Selection tab is used to select the records to be included in the analysis. If no selection statements are made on the Selection tab, all records in the database will be included. Selection statements reduce the number of records included in an analysis based on specific variables.

The Selection tab and Table tab are often confused; please read Selection Tab vs. Table Tab to avoid common mistakes.

Select Only (Standard Selections)

At the top of each Selection tab is a box with check boxes. The box is marked Select Only. These are the standard selections for the analysis of the database you have chosen. The View Statement link next to the box open the Standard Selection Details dialog describing the checked selections.

Malignant Behavior

Select this option to include only cases with a malignant behavior. The Behavior variable is part of the morphology of cancer. The SEER program only collects information on in situ and malignant cancers. If the behavior code is malignant, the case will be included in the analysis.

Male or Female Sex

Select this option to include only cases where sex is either Male of Female (for example no cases of unknown or transgender patients).

Known Age

Select this option to include only cases of a known age.

Cases in Research Database

Select this option to include only cases in the selected Research Database.

First Matching Record for Each Person

This option is only available for multiple primary ready databases. When First Matching Record for Each Person is checked, only the first record for each person which matches the selection criteria will be included in your analysis.

View Statements Link

This link opens the Standard Selection Details dialog, which provides the details of the standard options, indicates whether an option has been checked and shows if an option is disabled and the reason.

Creating Selection Statements in Rate Sessions

The Selection tab in a Rate session consists of three boxes. Click the Edit button next to each box to create or modify a selection statement in that box. Click the Clear button next to each box to delete its current selection statement.

Each variable in the database appears in only one of the three boxes on the Rate session's Selection tab.

When making selections in a Rate session, make your selection in the topmost possible box. For example, never make selections based on race or age in the case-only box at the bottom. That would result in erroneous statistics because inappropriate populations were used as the denominators in the calculations. (Note: a warning message will be displayed if you attempt to execute a session with this error. However, not all erroneous situations can be identified by SEER*Stat; therefore, you must exercise care.)
