Among 14 included studies (1,769 stroke and 7,400 nonstroke cases), the pooled OR estimate of ischemic stroke associated with hyper-Hcy was 1.79 (95% CI, 1.61 to 2.0; p < 0.001). Among 19 included studies (2,788 stroke and 3,962 nonstroke cases), the OR associated with the TT genotype was 1.23 (95% CI, 0.96 to 1.58; p = 0.1). Conclusion: These data support an association between mild-to-moderate hyper-Hcy and ischemic stoke. The MTHFR TT genotype may have a small influence in determining susceptibility to ischemic stoke.
