Figure 4. Kaplan-Meier survival curve analysis for patients with low-perfused (continuous line) or high-perfused (dashed line) gliomas (pooled patients irrespectively of tumor surgery).

The patients were stratified in two groups according to the optimal mTBF cut-off value from the ROC curve analysis. Patients with low-perfused gliomas had significantly longer EFS compared to patients with high-perfused gliomas (P = 0.0012).
