Data are n (%) or mean ± SD or median (interquartile range). BMI, body mass index; VLDL-C, very low-density lipoprotein cholesterol; LDL-C, low-density lipoprotein cholesterol; LDL I + II, low-density lipoprotein subclasses I and II; LDL III, low-density lipoprotein subclass III; LDL IV, low-density lipoprotein subclass IV; HDL-C, high-density lipoprotein cholesterol. Means were compared between non-obese and obese groups by Independent-Sample T test, except LDL IV when p values were calculated from Mann–Whitney U test. P-values were adjusted for age and gender by Binary Logistic Regression.
