Verification of the risk model in the CGGA cohort. A Distribution of risk scores for glioma patients in the CGGA cohort. B PCA plot for CGGA patients based on the risk score. C The distribution of patient status in the CGGA cohort (the dots represent the status of the patient, sorted by the increase in risk score). Low-risk cases: the left side of the dotted line; high-risk cases: the right side of the dotted line). D Mortality rates among the high-risk and low-risk groups. E Kaplan-Meier curve of the high-risk and low-risk groups. F The ROC curve shows the predictive efficiency of the risk model
