The prognostic results of IRGs-based RiskScore in Train 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 receiver operating characteristic (ROC) curve indicated prognostic results in train group. The area under curve (AUC) corresponding to 1-, 3- and 5-year survival was provided.
