The calibration curves of the nomogram for the 3-, 5-, and 10-year OS prediction of the training queue (A–C), internal verification queue (D–F), and external verification queue (G–I). The OS probability predicted by the nomogram is plotted on the X-axis, and the actual probability is plotted on the Y-axis. The dotted line (plotted by y = x) shows the agreement of the actual result with the predicted result
