Construction and calibration of nomogram in HNSC patients. (A) Comparison of the predictive power of the prognostic models in entire TCGA cohort. C-index: Harrell’s concordance index; CI: confidence interval. Combined model: IRGPI + age + gender + tumor status + tumor grade + pathological stage + T stage + N stage. (B) Nomogram to predict 1-, 3-, and 5-year OS in entire TCGA cohort. (C-E) Calibration curves of nomogram on the consistency between predictive and observed 1-, 3-, and 5-year outcomes in entire TCGA cohort. Dashed line at 45° indicated perfect prediction. Actual performances of the nomogram were shown in blue lines. (For interpretation of the references to colour in this figure legend, the reader is referred to the web version of this article.)
