Establishment and validation of the prognostic model for OS of patients in the training set, the test set, and the entire cohort. (A) The distribution of risk scores, gene expression levels, and patient relapse status; (B) Kaplan–Meier curves of DFS of the low- and high-risk groups; (C) ROC curve for the 1-, 2-, 3-, 4-, and 5-year survival prediction by the four-gene signature, respectively. The black dotted line represents the median risk score cutoff dividing patients into low- and high- groups
