Multivariate logistic analysis revealed that the AIP, as a continuity variable (OR 1.55, 95% CI, 1.35–1.82, p = 0.009), was independently associated with poor outcomes at 3 months after the adjustment for age, gender, baseline NIHSS, reperfusion therapy, history of lipid-lowering therapy, history of atrial fibrillation, and history of diabetes mellitus, glucose, TC, and LDL-C. The gene discussed is AIP; the disease is atrial fibrillation.
