Kaplan-Meier survival analysis in 76 patients with gliomas. a Kaplan-Meier curve showing the patients with high-grade tumor have a lower survival rate than those with low-grade tumor. b Patients with a tumor with high HGF expression had a lower survival rates than those with low HGF expression tumors. c A significant difference in survival rates was found between patients with a high proliferation index and low index in their tumor. d There was no significant difference in survival rates between the patients with or without tumor recurrence.
