The significant associations between the rs693 polymorphism and higher levels of APOB (SMD = 0.25, 95% CI = 0.12–0.38, P < 0.01), TG (SMD = 0.09, 95% CI = 0.00–0.18, P = 0.04) and LDL-C (SMD = 0.23, 95% CI = 0.13–0.33, P < 0.01) were detected in the healthy/control subjects, but not in the patients with CHD. The gene discussed is APOB; the disease is coronary artery disorder.
