Values are presented as median (interquartile range) or n (%).ApoAI, Apolipoprotein AI; ApoB, Apolipoprotein B; BMI, body mass index; HDL-C, high-density lipoprotein cholesterol; LDL-C, low-density lipoprotein cholesterol; Lp(a), Lipoprotein(a); Non-HDL-C, non-high-density lipoprotein cholesterol; RC, remnant cholesterol; TC, total cholesterol; TG, triglycerides. For each quantitative variable, the P-value is obtained by the Mann-Whitney U-test; for each categorical variable, the P-value is obtained through Pearson's χ2-test.
