In patients with GBM, though the OS of patients in the low-expression group was longer (P = 0.092, Additional file 1: Fig. S4C) than that of high-expression group in the CGGA dataset, the median expression level of eIF3i cannot stratify the OS (P = 0.305, Additional file 1: Fig. S4F) of patients in TCGA dataset. Here, EIF3I is linked to glioblastoma.
