  1. Data are presented as mean (SD) or median (first quartile to the third quartile) for continuous variables or n (%) for counting data
  2. aIndicates that the datum is subject to normal distribution and homogeneity of variance test and is presented as mean (SD). Multiple tumors refer to the number of bladder tumor ≥ 2. Abbreviations: BMI, body mass index; CHD, coronary atherosclerotic heart disease; FHC, family history of cancer; EORTC, European Organization Research and Treatment of Cancer Scoring system, _R refer to recurrence and _P refer to progression; HER, recurrence score of EORTC ≥ 5; HEP, progression score of EORTC ≥ 7
