Adjusted for age, stage, grade, deprivation index, time period and whether chemotherapy was received (all continuous variables were categorised before analyses; categories were same as presented in Table 1).
Tested also for travel time and whether hormone therapy was received, but were dropped from the final analysis as they did not have significant effect on relative risks of death.
