From: The frequency and prognostic effect of TERT promoter mutation in diffuse gliomas
a) All gliomas included in this study showed statistically different survival. b) Among patients with grade III anaplastic astrocytoma (AA), the IDH-mutant group showed remarkably better survival than IDH-WT group. c) The IDH-mutant grade IV GBM group had significantly better survival compared to the IDH-WT GBM group. d) Of all patients with grade III and IV astrocytic tumors, MGMTp-methylated groups have statistically better survival (P = 0.017). e and f) However, when GBM is subdivided into IDH-mutant and IDH-WT, MGMTp-methylation has a modest survival effect (P = 0.051 and P = 0.076, respectively). These results indicate there is no bias effect associated with our group
