Fig. 4

The calibration curves for predicting patient survival of the training cohort at 1-, 3-, 5-year, 7-year, 10-year point. Nomogram-predicted cancer specific survival is plotted on the x-axis; actual cancer specific 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
