Table 1. G-CIMP and IDH1 mutation status in primary, secondary, and recurrent GBMs.

G-CIMP and IDH1 mutation status are compared for All analyzed GBM tumors (p< 2.2x10⁻¹⁶), Primary tumors, Recurrent tumors, and Secondary tumors. P value is calculated from Fisher’s exact test. See also Figure S3 and Table S2.
