TURB – transurethral resection of bladder tumour, CIS – carcinoma in situ, HR – hazard ratio, 95% CI – 95% confidence interval, the value of adjusted p < 0.05 was considered statistically significant (bolded); HR > 1 better outcome when reTURB performed, HR < 1 worse outcome when reTURB performed, n.s. – non-significant.
