Fig. 5From: Clinical impact of IDH1 mutations and MGMT methylation in adult glioblastomaReceiver operating characteristic (ROC) curve for MGMT methylation among investigated groups. Arrow contributes to the best cutoff point that discriminates between high methylation (≥ 66%) versus low–moderate methylation at area under the curve (AUC) = 0.837, 95%CI = 0.723–0.917, at P = 0.0001Back to article page
