OS in patients with HNSCC. (A) Nomogram for predicting the probabilities of 1-, 3-, and 5-year OS. (B) Calibration curves suggest that the nomogram demonstrates high accuracy in predicting 1-, 3-, and 5-year OS. (C) DCA shows that the nomogram potentially provides better prediction of OS in patients compared with the use of individual prognostic factors. OS, overall survival; HNSCC, head and neck squamous cell carcinoma; DCA, decision curve analysis
