Figure 3

Calibration plots of nomogram to predict 3- and 5-year overall survival (OS) in training (A,B) and validation cohorts (C,D). The X-axis indicated nomogram-predictive survival; the Y-axis suggested actual CSS. A plot with 45-degree line was suggestive of a perfect calibration where predictive possibilities were identical to actual ones. Vertical bars indicated 95% CIs.
