In addition, analyses using Pearson's chi‐squared test (Table 2) demonstrated that higher risk score was significantly linked to higher tumor grades (grade III, p < 0.001), WT IDH (p < 0.001), non‐codel status of 1p19q (p < 0.001), non‐methylation status of the MGMT promoter (p < 0.001), and WT status of TERT (p < 0.001). This evidence concerns the gene IDH2 and neoplasm.
