Analysis of independent prognostic factors and establishment and validation of the prediction model. A Univariate COX shows that SLC25A17 expression, age, stage, T stage and lymph node metastasis were prognostic risk factors; B multivariate COX shows that SLC25A17 expression, age, and lymph node metastasis were prognostic risk factors; C, D survival prediction nomogram based on TCGA-HNSC cohorts and 1-, 3-, and 5-year survival calibration curves. E The C-index of the nomogram and other clinical features in TCGA-HNSC cohorts. F, G Survival prediction nomogram based on the GSE65858 cohort and 1-, 3-, and 5-year survival calibration curves. H The C-index of the nomogram and other clinical features in the GSE65858 cohort
