A, Kaplan–Meier overall survival analysis of GBM patients in the validation cohort (n=224). Survival among miR-148a-Methylated (n=29, solid line) and miR-148a-Unmethylated (n=195, dotted line) patients is shown. B, Kaplan–Meier overall survival analysis of Grade III glioma patients in the validation cohort (n=42, solid line). Survival among miR-148a-Methylated (n=30) and miR-148a-Unmethylated (n=12, dotted line) patients is shown.
