CIMT: carotid artery intima-media thickness, BP: blood pressure, LDL: low-density lipoprotein, HDL: high-density lipoprotein. Simple: Pearson's correlation coefficient (r), multi-adjusted: a multiple linear regression coefficient (β). The CIMT, triglycerides, Lp(a) and oxidized Lp(a) levels were calculated after a log-transformation. Significance level: * P ≤ 0.05, ** P ≤ 0.01.
