KM survival analysis, risk score assessment by the MRGs risk signature and time- dependent ROC curve in the training set. A KM survival analysis of high- and low- risk samples in the training set. Patients in high‐risk group had a shorter OS compared to those in low‐ risk group. B Risk scores, survival status distribution, and heat map for prognosis-associated metabolic genes of patients with OSCC in the training set. C ROC curve analysis results show the accuracy and reliability of the prognostic signature in determining the 1, 3 and 5 years survival outcomes (AUC values are shown in parentheses). D ROC curves of the prognostic signature and clinical risk factors for 1 year survival
