A.ROC curve of the Nomogram and 8th TNM Stage in prediction of prognosis of patients at 1, 3 and 5 year point in the 2004–2010 cohort. B. The calibration curves for predicting patient survival at 1, 3 and 5 year point in the 2004–2010 cohort. Nomogram-predicted cancer specific survival is plotted on the x-axis; actual cancer specific survival is plotted on the y-axis. A plot along the 45-degree line would indicate a perfect calibration model in which the predicted probabilities are identical to the actual outcomes. ROC: receiver operating characteristic curve; AUC: areas under the ROC curve.
