Identification of the independent prognostic parameters and construction of a gene-based prognostic model. (A) Forest plot of univariate Cox regression analysis in HNSCC. (B) Forest plot of multivariate Cox regression analysis in HNSCC. (C) ROC analysis indicated that risk score and age were accurate variables for survival prediction. (D) Formula to build the models. (E–G) Calibration curves showed the concordance between 1-, 3- and 5-year OS prediction and observation of the two models. (H) ROC analysis showed that the model combining M stage and risk score was an accurate variable for survival prediction. (I) Nomogram integrating six gene-based M stages and a risk score.
