From: Nomogram prediction of individual prognosis of patients with hepatocellular carcinoma
The calibration curve of overall survival at 1, 2, and 3 years for the primary cohort (a-c) and the prospective validation cohort (d-f). Nomogram-predicted probability of survival is plotted on the x-axis, and the actual survival is plotted on the y-axis. Dashed lines along the 45° line through the point of origin represent the perfect calibration models where the predicted probabilities are identical to the actual probabilities
