In addition, the correlation between WEE2-AS1 expression and major clinicopathological factors, including age (≤ 60 vs. >60, p = 0.01), WHO grade (G2 vs. G3 and G4, p < 0.001), histological type (astrocytoma, oligoastrocytoma, oligodendroglioma vs. glioblastoma, p < 0.001), IDH status (WT vs. Mut, p < 0.001), 1p/19q codeletion status (Codel vs. Non-codel, p < 0.001), and EGFR (WT vs. Mut, p < 0.001) were further determined by using logistic regression, as shown in Table 2. This evidence concerns the gene IDH1 and astrocytoma (excluding glioblastoma).
