Evaluation of the selenium metabolism gene-mediated model in the training cohort. A Univariate and multivariate regression analyses of the selenium metabolism gene-mediated model and clinical characteristics in the TCGA training cohort. Only factors with p values less than 0.05 in univariate analysis were included in multivariate analysis. B Comparison of the AUCs of the selenium metabolism model and clinical characteristics such as age, sex and pathological stage. C Comparison of the C-indexes of the selenium metabolism gene-mediated model and clinical characteristics such as age, sex and pathological stage. D A nomogram for predicting the 1-, 3-, and 5-year survival probabilities was constructed by using the selenium metabolism model and pathological stage. E Calibration curves of the nomogram. F Comparison of the AUCs of the selenium metabolism gene-mediated model, pathological stage, and nomogram at 1, 3, and 5 years
