Abstract Title:
Vitamin D serum levels in patients with migraine: A meta-analysis.
Abstract:
BACKGROUND/PURPOSE: Dietary habits and nutrients have been associated with migraine. The present study comprises a meta-analysis of observational studies evaluating serum levels of 25-hydroxyvitamin D (25(OH)D) in patients with migraine and healthy controls.METHODS: MEDLINE and Cochrane databases were comprehensively searched. References from retrieved observational studies, reviews and meta-analyses were manually screened. Quality assessment was performed based on the Newcastle-Ottawa Scale. 25(OH)D concentrations were assessed by estimates of mean differences (MD) and their precision [95% confidence intervals (95% CIs)]. Random effects (RE) or fixed effects (FE) model was used based on heterogeneity among trials (homogeneity determined when PQ>0.1 and I2
