Adiponectin gene polymorphisms contributes to ischemic stroke risk: A meta-analysis

Abstract

Background: Previous studies have reported the relation between the adiponectin polymorphisms and the risk of ischemic stroke. However, the findings is inclusive. In the present study, we performed a meta-analysis to clarify the relation between the adiponectin polymorphisms and the stroke. Methods: Relevant studies were identified by searching PubMed, EMBASE, ISI Web of Science, ScienceDirect, Wiley Online Library, Wanfang database in China, and Chinese National Knowledge Infrastructure databases (CNKI) through July 2013 and other method such as reviewing the reference of retrieved literatures. We selected literatures that reported Odds ratio (OR) and 95% confidence interval (CI) for the relation between the ischemic stroke and the adiponectin genetic polymorphisms. With 1720 stroke cases and 5549 controls, were included. Our results showed that rs2241766 was associated with the risk of ischemic stroke in a recessive model (GG vs (TT+TG), OR = 1.29, 95% CI: 1.01-1.64, p = 0.04). However, rs1501299 and rs266729 were not found to be associated with ischemic stroke in our analysis. Conclusion: The present study suggested that rs2241766 polymorphism of adiponectin gene was associated with the risk for ischemic stroke.
