Overall, the combined results showed no significant association between the CYP11B2 C-344T polymorphism and ischemic stroke for all genetic models (allelic model: OR = 1.19, 95% CI = 0.95–1.49; additive model: OR = 1.43, 95% CI = 0.91–2.27; dominant model: OR = 1.30, 95% CI = 0.89–1.89; and recessive model: OR = 1.24, 95% CI = 0.96–1.60). The gene discussed is CYP11B2; the disease is ischemic stroke.
