Abbreviations: HDL-C, high density lipoprotein cholesterol; LDL-C, low density lipoprotein cholesterol; NA, not available; TC, total cholesterol; TG, triglycerides.

^a High risk level was defined as ≥ 6.19 mmol/L for TC, ≥ 2.26 mmol/L for TG, ≥ 5.15 mmol/L for non-HDL-C, and < 1.04 mmol/L for HDL-C, ≥ 2.18 for TG/HDL-C, and ≥ 5.97 for TC/HDL-C.

^b Values are adjusted for age, propensity score, examination cycle, body mass index, current smoking, hypertension, diabetes and TC (in analyses of HDL-C and TG), using covariates from the examination in question.

^c Data were derived from the Kheirandish et al. findings (15).
