Validation of IRPLS as an independent predictor and construction of a novel nomogram for predicting OS. A‐C, Kaplan‐Meier survival analysis was used to show the significant prognostic value in the entire cohort, the testing cohort and the training cohort. D‐F, ROC analysis showed the AUC values for 3‐, 5‐ and 7‐year OS of 3 cohorts. G‐H, Both the univariate Cox regression analysis and the multivariate Cox regression analysis integrating major clinical characteristics with IRPLS were performed to demonstrate the independence factors for OS in BLCA. I, A nomogram was developed to predict 3‐, 5‐ and 7‐year OS using the IRPLS riskScore and the aforementioned clinical factors. J‐L, ROC analysis showed the AUC values for 3‐, 5‐ and 7‐year OS of the nomogram
