A Nomogram illustrating clinical variables and RiskScore. The nomogram calculates the probability of 1-year, 3-year, and 5-year OS by summing the points for each variable on the scale. B Calibration curve for predicting 1-year, 3-year, and 5-year OS in patients with HNSCC; C Time-dependent ROC curve analysis assessing the accuracy of the nomograms; D Decision curve analysis (DCA) curves intuitively evaluate the clinical benefit of the nomograms and their potential scope of application in obtaining clinical benefits. The calculated net benefits (Y-axis) are plotted against the threshold probabilities of patients having 5-year survival on the X-axis
