Background: This systematic review and meta-analysis evaluates peripheral and CNS BDNF levels in glioma patients.

Methods: Following PRISMA guidelines, we systematically searched databases for studies measuring BDNF in glioma patients and controls. After screening and data extraction, we conducted quality assessment, meta-analysis, and meta-regression.
