1-, 3-, 5- and 8-year OS calibration plots for BC patients based on the nomogram prognostic model. A The calibration plot for predicting BC patient 1‐year OS. B The calibration plot for predicting BC patient 3‐year OS. C The calibration plot for predicting BC patient 5‐year OS. D The calibration plot for predicting BC patient 8‐year OS. The Y‐axis indicates the actual survival of BC patients, and the X‐axis represents the nomogram‐predicted survival. The 45° line represents the best prediction value. The closer the curve is, the more ideal the result is. BC, bladder cancer; OS, overall survival
