Footnote
*Geometric mean was not calculated because the chemical was found in less than 65% of the study group
‡SAPEP collected multiple urine samples from study participants. The geometric means were estimated using random effects models to account for multiple samples per participant. Percentiles and detection frequencies were based on the total number of samples collected.
