Model 1; adjusted for age, gender, LDL and HDL cholesterol, triglycerides, waist circumference, hypertension, smoking and apoB/apoA-I ratio for both ethnic groups. Model 2; adjusted for Model 1 with an addition of metabolic syndrome for both ethnic groups. Apo, apolipoprotein; LDL, low-density lipoprotein; NS, non significant.
