MP-SIR Table Tab

A results matrix consists of one or more tables containing the statistics calculated by SEER*Stat, which can be stratified by the variables of your choice. The Table tab is used to determine which variables are used to stratify the results.

The Table tab in an MP-SIR session has different controls depending on the type of statistic you have chosen to calculate on the Statistic tab.

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

When SIR Tables are Being Generated

The default setting in MP-SIR sessions is for the results matrix to contain SIR (Standardized Incidence Ratio) tables.

Display Variables

Select variables from the Event and Time Dependent Variables or Cohort Stratification Variables boxes, and use the buttons on the right to add them to the Display Variables box.

Row, column, and page variables that you choose here will appear in the row, column, and page dimensions of the MP-SIR matrix.

Event and Time Dependent Variables

The calculated time-dependent and event variables used in MP-SIR sessions are available in this box. Unlike the cohort stratification variables, these variables' values are not stored in the database, but are generated by SEER*Stat during execution. Highlight one of these variables and click Page, Row, or Column to place it in the corresponding position.

If you include the Attained Age, Attained Calendar Year, or Latency variables in the table, you must define cut-points for them on the Parameters tab, or SEER*Stat will not be able to perform the analysis. If you define cut-points but do not include the corresponding variable in the table, SEER*Stat will be able to perform the analysis, but will issue a warning when you execute the session to inform you of this possible oversight.

Cohort Stratification Variables (From Index Record)

Standard, user-defined, and merged variables from the dictionary are available in this box. Note that values of cohort stratification variables such as Age at Diagnosis remain constant throughout the analysis since they are taken from the subject's index record, not from event records.

Note: There are limits to the number of variables that you can display in tables.

Moving Variables Up and Down

If you have multiple variables in one position (row, column, or page), then the order of the variables in the output table is determined by the order in which they are listed here. Highlight a variable and click Move Up or Move Down to change the order of the variables, or to move a variable from one position to another.

Note: Variables in a row or column can also be reordered after the session has been executed.

Removing a Variable

To remove a variable from the table, highlight the variable in the Display Variables box and click Remove, or use the Delete key. You can remove all of the variables in a given position by highlighting that position and clicking Remove.

When Frequencies are Being Generated

When the Frequencies option is selected on the Statistic tab in an MP-SIR session, the Table tab has similar controls to those available when SIR tables are being calculated.  However, there are some important differences.

Event and time-dependent variables are not used, so in place of that box, there is a Calculated Variables box. Depending on your settings on the Statistic tab, the Calculated Variables box contains some of the following variables:

There is an additional check box, Index Record, next to the Cohort Stratification Variables box. If the option to count Only the Index Record is chosen on the Statistic tab, this check box will always be checked and disabled. If the option to count Only Non-Index Records is chosen, you can mark this box to include cohort stratification variables from the subject's index record in the table along with the data from their event records. To do so, highlight the variable in the Cohort Stratification Variables box, then mark this check box before clicking Page, Row, or Column. Note that variables from the index record are prefixed with "Index Record." in the Display Variables box. Otherwise, the individual non-index records are used for stratification.

When a Case Listing is Being Generated

When the Case Listing option is selected on the Statistic tab in an MP-SIR session, the Table tab resembles a Case Listing Table tab, with the following differences:
