The results of univariate Cox regression analysis were shown in Supplementary Table S1: TIPE2 expression (p = 0.033) was a protective factor for progression-free survival of bladder urothelial carcinoma, while pT stage (p = 0.004), age (p = 0.023) and lymph node status (p = 0.033) were risk factors for progression-free survival of bladder urothelial carcinoma. This evidence concerns the gene TIPE2 and bladder transitional cell carcinoma.
