EIF4E1B and glioblastoma: To test this notion, we subdivided patients into EIF4E1B-high and EIF4E1B-low expression groups based on cutoff values determined by the “surv_cutpoint” function of R package “survminer” (0.1252297 for GBM and 0.02686604 for LGG) and compared the survival difference by the Kaplan-Meier method.
