Fig. 2

Calibration plots for predicting 5-Year PFS of patients with NPC in training cohort (a) and validation cohort (b). Nomogram-1 predicted 5-Year PFS is plotted on the x-axis, and observed 5-Year PFS is plotted on the y-axis. Dashed lines represent the perfect calibration models, in which the predicted probabilities are identical to the observed probabilities. Abbreviations: PFS, progression-free survival; NPC, nasopharyngeal carcinoma
