Construction and validation of nomogram. (A) The ROC curve was performed to verify the predictive performance of predictive model. (B,C) Univariate/multivariate Cox regression model was constructed to verify the independent predictive performance of each parameter in TCGA-BLCA cohort. (D–F) ROC curve and Univariate/multivariate Cox regression model were plotted to verify in GEO database. (G) Construction of a nomogram combining M stage and risk score. (H,I) Calibration plot showing that nomogram-predicted survival probabilities corresponded closely to the observed proportions.
