MP-SIR Selection Tab

The Selection tab in an MP-SIR session is used to define the cohort to be analyzed by specifying criteria for an index record.

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

The Selection tab in an MP-SIR session consists of one standard selection statement box, and shortcuts for some common selections.

Standard Index Record Selections

The Standard Index Record Selections section of the Selection tab provides shortcuts for common index record selections. It is possible, but not necessary, to build a selection statement in the Additional Index Record Selections box that is equivalent to any of the options in this section.

The index record in an MP-SIR session defines cohort members and is the first record that matches the selection criteria. Use the drop-down list to choose what should be considered a "first record" for the purposes of this analysis.

Additional Index Record Selections

Create a selection statement in this box to limit the records included in your analysis based on variables not covered by the standard index record selections.

To begin building a selection statement, click the Edit button at the right. If there is no selection statement, all cases in the database which match the standard selections you made above will be included in your analysis. Therefore, you should only make a selection statement for variables used to exclude cases. To clear the entire statement from the selection box, click Clear.
