Hazard ratios (HRs) for cancer specific deaths and for other deaths associated with smoking and non-steroidal anti-inflammatory drugs (NSAIDS) use status, stratified by history radiation therapy (striped bars: no radiation, solid bars: radiation). The extended lines from the top of the bars indicate 95% confidence intervals. The "n" in the parentheses indicates the numbers of each event for no radiation and radiation groups and the p-values in the parentheses those for the interactions between smoking/NSAIDS with radiation therapy status and causes of deaths.
