ATRX mutation was not a statistically significant biomarker in all grade III and IV astrocytic tumors. a) In cases with grade III anaplastic astrocytoma, combined IDH-mutant and –WT tumors, the ATRX-mutant group does not show statistically different OS compared to the ATRX-WT group (P = 0.780), b) a finding which is comparable to that found in the GBM IDH-WT group (P = 0.419). c, d) Statistical significance of age were obtained in the group 4 (AA, IDH-wildtype) (P = 0.029), and the group 5 (IDH-WT GBMs) (P = 0.016), patients older than 55 years have a statistically significant worse OS compared to patients younger than 55 years of age
