Calibration plot of the esophageal cancer prediction models in the Changzhou cohort. Calibration of the original (A) age-only, (C) simple, and (E) intermediate models. Calibration of the recalibrated (B) age-only, (D) simple, and (F) intermediate models. The observed 10-year risk was estimated by Kaplan-Meier analysis and plotted against model-predicted risk by decile.
