Construction of the risk model based on 3 key genes. (A) The forest plot of the univariate Cox analyses of the 3 key genes. (p-value < 0.05) (B) Least absolute shrinkage and selection operator (LASSO) analysis of the 3 key genes with minimum lambda value. (C-F) The risk score (C), heat map (D), Kaplan-Meier (K-M) survival (E), and time-dependent receiver operating characteristic (ROC) curves of overall surviva (OS) (F) in the GSE28042 dataset. The area under curve (AUC) was assessed at 1, 2 and 3 years
