CI, confidence interval; TAC, total dietary antioxidant capacity; Hb, hemoglobin; TC, total cholesterol; TG, triglyceride; LDL, low density lipoprotein cholesterol; HDL, high density lipoprotein cholesterol; HCT, hematocrit; BUN, blood urea nitrogen; Lp, lipoprotein; CRP, C-reactive protein. The multivariate multinomial logistic regression was used for estimation of ORs and confidence interval (CI) with adjustment for the confounding effects of age, gender, BMI and presence of diabetes and myocardial infarction. Bold digits indicate statistically significant values as P < 0.05.
