^a

Urinary metabolites are normalized to specific gravity.

^b

MDL = method detection limit of the analyte; # (%) < MDL = number and percentage of participants with concentrations below the MDL.

^c

Percent calculated is # < MDL divided by 96 for mothers and by 90 for children.

^d

LOD = method detection limit of the analyte; # (%) < LOD = number and percentage of participants with concentrations below the LOD.

^e

Percent calculated is # < LOD divided by 38 for mothers and for children.
