Figure 3. Development of the prognostic model based on ERDEGs. (A) Univariate Cox analysis filtered out 19 ERDEGs correlated with GBM patients’ survival. (B, C) LASSO regression analysis revealed that 9 ERDEGs were prognosis-related genes (PRGs) of GBM patients. (D) Distribution of patients based on the risk score in the training dataset. (E) Survival time and status of patients in the training dataset. (F, G) The Kaplan-Meier (K-M) survival curve and ROC curve in the training dataset.
