Abstract
Background: Epidemiological studies evaluating the association between vitamin E intake and glioma risk have produced inconsistent results. Thus, we conducted a meta-analysis to summarize the evidence from epidemiological studies of vitamin E intake with the risk of glioma. Methods: Pertinent studies were identified by a search in pubmed and web of knowledge up to August 2014. The random-effect model was used to combine the results. Publication bias was estimated using the Egger's regression asymmetry test. Results: Twelve studies including 3180 glioma cases about vitamin E intake with the risk of glioma were included in this meta-analysis. The combined relative risk (RR) of glioma associated with vitamin E intake was 0.88 (95% CI = 0.69-1.12). The association was significant neither in the case-control studies nor in the cohort studies. No publication biases were found. Conclusions: Our analysis indicated that vitamin E intake is not associated with the risk of glioma.
