Abbreviation: CI, confidence interval; GM, geometric mean; HDL-C, high-density lipoprotein cholesterol; LDL-C, low-density lipoprotein; TC, total cholesterol; TG, triglyceride. ^∗p values designate differences of covariance (ANCOVA) between three groups. ^∗∗p values of the comparison between borderline or high groups with the healthy group by ANCOVA with post hoc analysis (LSD method). ^∗∗∗Geometric mean and 95% confidence intervals of YKL-40 were calculated by ANCOVA adjusting for gender (boy and girl) and age with LSD method. Numbers in bold indicate significant differences (p < 0.05).
