Moreover, CYP1A2 rs2470890 was associated with stroke risk in the codominant (adjusted OR = 1.91, 95% CI: 1.11–3.27, P = 0.019), dominant (adjusted OR = 1.85, 95% CI: 1.10–3.10, P = 0.021) and log-additive (adjusted OR = 1.67, 95% CI: 1.04–2.70, P = 0.035) models. The gene discussed is CYP1A2; the disease is Stroke.
