Evaluation of prognostic model in the TCGA-testing set and functional enrichment analysis of DEGs between the risk groups. A The risk score, survival time, survival status, and 3-gene expression trend in the testing set (TCGA, 176 samples). B ROC curves for the sensitivity and specificity of one-, two-, and three-year OS according to the risk score in the testing set. C Kaplan–Meier curve for OS between the high- and low-risk groups in the testing set. D Volcano plot of DEGs between the high-risk and low-risk groups from TCGA data set. E The Chord of eight significantly enriched GO terms between high-risk and low-risk groups
