Figure 1. Proportion and Kaplan-Meier survival analyses of molecular groups in diffuse infiltrative gliomas. Survival proportions in infiltrative (Grade II-IV) gliomas (A), lower-grade (Grade II-III) gliomas (B), and Grade IV glioma (C). (D) Kaplan-Meier OS curves in lower-grade gliomas. OS estimates for the 5 molecular groups are significantly different (P < 0.001). (E) Kaplan-Meier OS curves in Grade IV glioma. No differences in OS were detected for the 3 molecular groups (P = 0.285).
