Statistics in an MP-SIR Matrix

An MP-SIR results matrix consists of Standardized Incidence Ratio tables which provide the following statistics for your cohort. The display of these statistics may be enabled or suppressed on an individual basis using the Matrix Options dialog.

((Observed count - Expected count) x 10,000) / Person years at risk

Note that for sex-specific sites, the excess risk statistic will be incorrect if the person years at risk is not sex-specific. For example, if showing statistics by cancer site and sex, the statistics for both sexes combined for sites such as prostate, cervix, etc. will be incorrect.
