Calibration curves used to compare the nomogram-predicted and actual measured survival probabilities at 1 year and 2 years for the validation cohort (5A and 5B, respectively). The y-axis represents the actual measured survival probability, and the x-axis represents the nomogram-predicted survival probability. The diagonal dotted line represents a perfect prediction by an ideal model. The red solid line represents the performance of the nomogram; a closer fit to the diagonal dotted line represents a better prediction
