Meta-Analysis on the Association between Brain-Derived Neurotrophic Factor Polymorphism rs6265 and Ischemic Stroke, Poststroke Depression

Thus, brain-derived neurotrophic factor rs6265 might be recommended as a predictor of susceptibility of ischemic stroke. However, the results of this meta-analysis should be interpreted with caution because of the heterogeneity between studies and low sample size. Further studies are needed to evaluate the associations between rs6265 and poststroke depression, especially in Caucasians, with large sample size.
