Furthermore, we also noticed that there was a tendency that the patients with low-expression of eIF3i had longer OS than patients with high-expression of eIF3i in both 1p/19q co-deleted, IDH-mutant oligodendroglioma (P = 0.09 for CGGA and P = 0.123 for TCGA, Fig. 4 C and G) and 1p/19q non-codeletion IDH-mutant astrocytoma (P < 0.001 for CGGA and P = 0.203 for TCGA, Fig. 4d, h). This evidence concerns the gene EIF3I and astrocytoma (excluding glioblastoma).
