Hazard ratios (HR) for cancer-specific death are shown with their 95% confidence intervals (CI) and corresponding p values of the Wald statistic from the models
p values < 0.05 were considered statistically significant
cN clinical lymph node status, pN pathological lymph node status, ypT pathological T stage after chemotherapy and cystectomy,
