Association between vitamins and risk of brain tumors: A systematic review and dose-response meta-analysis of observational studies.

ABSTRACT:

Background

Brain tumor is one of the important causes of cancer mortality, and the prognosis is poor. Therefore, early prevention of brain tumors is the key to reducing mortality due to brain tumors.

Objective

This review aims to quantitatively evaluate the association between vitamins and brain tumors by meta-analysis.

We searched articles on PubMed, Cochrane Library, Web of Science, and Embase databases from inception to 19 December 2021.
