Fig. 1 Cumulative mortality curves for overall mortality (deaths from all causes), bladder cancer–specific mortality (deaths due to uncontrolled bladder cancer progression), and competing mortality (deaths in the absence of uncontrolled bladder cancer progression) stratified by smoking status. Univariate analyses revealed no detectable differences among current smokers, former smokers, and nonsmokers (log-rank test and Pepe-Mori test, p values ranging between 0.1804 and 0.7678).
