^aNumber of deaths.

^bStandardized mortality ratio.

^c95% confidence interval.

^dRelative risk of mortality (relative risks and 95% confidence intervals for lymphatic/hematopoietic cancers were calculated based on standardized mortality rate regression).

^eRelative risk and 95% confidence intervals were not presented due to small number of deaths among no RT group.
