RS: relative survival point estimate, SE: standard error of the estimate, RER: relative excess risk women vs. men, CI: confidence interval.
*adjusting for age, stage and subsite, including interaction of sex with age and sex with subsite.
Estimates of relative excess risk (RER) associated with female sex were derived using multivariate model* (‘Colon - unspecified/other’ subsite cases were omitted).
