^a.

GM values reported are based on detectable concentrations, including instrumental reading values, for each biomarker.

^b.

ICC _n≥2 (95%CI): indicates ICC values and respective 95% confidence intervals based on data from children who provided 2 or more samples during the 12-month follow-up period.

Abbreviations: LOD- Limit of detection; %LOD- Percent of samples with concentrations above the limit of detection for each specified analyte; GM- geometric mean; GSD: geometric standard deviation; 95%CI: 95% confidence interval; ICC: Intraclass correlation coefficient.
