**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.
