Figure 5. Nomogram, calibration plot, and DCA curves. (A) Nomogram assembled from the training set to predict 1-, 3-, and 5-year recurrence-free survival probability. (B–D) The calibration plot of the nomogram for predicting the recurrence-free survival probability at 1- (B), 3- (C), and 5-year (D). (E) The time-dependent ROC curves of the nomogram for predicting the recurrence-free survival at 1-, 3-, and 5-year. (F–H) DCA curve shows that the combined model exhibited the highest net benefit for 1- (F), 3- (G), and 5-year (H) RFS prediction.
