Background:
Stroke is the second highest cause of morbidity and functional disability around the world. In addition, it is the second most common cause of death worldwide [ 1 ]. However, the genetic pathology of stroke is still unclear. Published data on the association between TNF-a 238G/A polymorphisms and ischemic stroke risk are inconsistent and controversial. To provide a more robust estimate about TNF-a 238G/A polymorphisms on the risk of ischemic stroke, we conducted this meta-analysis.
Methods:
We used the pooled odds ratios (ORs) with 95% confidence intervals (95%CIs) to investigate the relationship between TNF-α238G/A polymorphisms and ischemic stroke. Publication bias was tested by Begg's test and inverted funnel plot, and Heterogeneity was checked by Cochran's Q statistic and the inconsistency index (I(2)).
Results:
There are 7 studies that include 1,766 cases and 1,560 controls in this meta-analysis. The results indicated a significant association between TNF-α238G/A polymorphisms and ischemic stroke in overall analysis, Caucasian and Adult. However, statistical association was not observed in Juvenile and Asian.
Conclusions:
This meta-analysis suggests that TNF-α238G/A polymorphisms increases the risk of ischemic stroke in Adult, Caucasian, and overall analysis. However, in Juvenile and Asian analysis, significant associations between TNF-α238G/A and ischemic stroke were not found.
