The validation of prognostic results in Test group
(A) Rank of prognostic index and distribution of high and low risk groups. (B) Survival status of patients in different groups. (C) Heatmap of expression profiles of included genes in high and low risk groups. (D) Patients in high-risk group showed shorter survival intervals. (E) Survival-dependent ROC curve indicated prognostic results in test group. The AUC corresponding to 1-, 3- and 5-year survival was provided.
