aAssumes that the within-woman GM gestational urinary
phthalate or BPA concentration is the gold standard. The surrogate
measure of low, medium, or high is defined by the first, second, or
third tertile of trimester-specific urine samples, respectively.
Probabilities are calculated from the top versus bottom two tertiles of
trimester-specific and average gestation urinary phthalate metabolite
and BPA concentrations. Limited to women with all three urine samples.
All concentrations are SG adjusted. bn = 77 for phthalates; n = 91 for
BPA. cPPV is the probability of being classified in the top tertile of
mean gestational phthalate metabolite or BPA concentration, given that
the woman’s trimester-specific urinary phthalate metabolite or BPA
concentration is in the top tertile. dΣDEHP metabolites: mono
2-ethyl-5-carboxypentyl phthalate (MECPP), mono 2-ethyl-5-hydroxyhexyl
phthalate (MEHHP), mono 2-ethyl-5-oxohexyl phthalate (MEOHP), and mono
2-ethylhexyl phthalate (MEHP). |
