Table 4.

Intercorrelations among % bound metabolite values

Metabolite	N	% Bound MEHP	% Bound 5-OH-MEHP	% Bound 5-oxo-MEHP	% Bound 5-cx-MEPP
% Bound MEHP	103	1.00
% Bound 5-OH MEHP	102	0.19	1.00
% Bound 5-oxo MEHP	103	−0.04	0.51*	1.00
% Bound 5-cx MEPP	99	−0.12	0.12	0.14	1.00

The % Bound MEHP, and % Bound 5-cx-MEPP indices were normally distributed, but the % Bound 5-OH-MEHP and % Bound 5-oxo-MEHP were negatively skewed. A log10 transformation based on first subtracting the values for these latter two % Bound indices from 100 and adding .05 was applied before correlating them with the other two indices

MEHP monoethylhexylphthalate, 5-OH MEHP 5-hydroxy-methylethylhexyl phthalate, 5-oxo MEHP 5-oxo-methylethylhexyl phthalate, 5-CX MEPP 5-carboxy-methylethylhexyl phthalate
