(A-C) The calibration curves of the nomogram for predicting 5-, 8-, 10-year (OS) of patients with PCa in the primary cohort. Nomogram-predicted 5-, 8-, 10-year survival is plotted on the x-axis; actual survival is plotted on the y-axis. A plot along the 45-degree line would indicate a perfect calibration model in which the predicted probabilities are identical to the actual outcomes. (D) 5-, 8-, and 10-year time-dependent ROC of the model. (E) Time-AUC of the model. (F) The ROC curve of the internal validation using the bootstrap method (resampling = 1000). Each gray curve in the figure represents the ROC curve of each resampling, and the blue line is the mean ROC curve of the model
