As depicted in Figure S1A,B, by using a CoxPH multifactor analysis, CERCAM was closely related to recurrence‐free survival (RFS; hazard ratio = 0.451, p = 0.032) and the overall survival (OS; hazard ratio = 0.281, p = 0.00013) in patients with bladder cancer. This evidence concerns the gene CERCAM and urinary bladder cancer.
