Interleukin-13 +1923C/T polymorphism is associated with asthma risk: a meta-analysis.

ABSTRACT: There are controversies on the association between interleukin-13 (IL-13) +1923C/T polymorphism (rs1295686) and the risk of asthma. We performed this study to assess the association by the method of meta-analysis. A systematic search current to October 16, 2012, was conducted using PubMed, EMBASE, and China National Knowledge Infrastructure (CNKI) and identified ten studies comprising 13698 cases and 38209 controls. The pooled odds ratios (ORs) with 95% confidence intervals (CIs) were calculated. There was a significant association between IL-13 +1923C/T polymorphism and asthma risk in codominant model. When stratified by ethnicity, IL-13 +1923C/T polymorphism remained significantly associated with higher asthma risk in Asians and Caucasians. In the subgroup analysis by study quality, a si
