  1. Values are mean (sd) or median (25th percentile; 75th percentile) for continuous variables with normal and non-normal distribution, respectively, and n (%) for categorical variables. (I) hsCRP < 0.016 mg/dl; (II) hsCRP 0.016 mg/dl and < 75th sex-specific percentile of those with hsCRP 0.016 mg/dl (< 0.085 mg/dl in girls; < 0.092 mg/dl in boys); and (III) hsCRP 75th sex-specific percentile of those with hsCRP 0.016 mg/dl (0.085 mg/dl in girls; 0.092 mg/dl in boys). Differences between females and males were tested by Student’s t-test (means) or Wilcoxon’s rank-sum test (medians) for continuous variables, and by Pearson’s Χ2-test for categorical variables. Significant p-values are marked in bold (p < 0.05)
