Prevalence and factors for food allergy in different populations from different regions: A protocol for a systematic review and meta-analysis.

ABSTRACT:

Background

To determine the prevalence of food allergy (FA) and factors associated with these occurrences in different populations from different regions.

Materials and methods

The literature search will be conducted via Pubmed, Embase, Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI), Vip and Wanfang databases. Ratio rate (RR), odds ratio (OR) and 95% confidence intervals (CIs) will be adopted to evaluate prevalence and factors for FA in different populations from different regions. When the heterogeneity is small (I2<50%), the fixed effect model will be analyzed, otherwise, random effects model analysis will be performed. When the heterogeneity is large (I2≥50%), Meta regression will be used to explore the sources of inter-study heterogeneit
