Covariate-Adjusted FRs for Maternal First Trimester Urinary Bisphenol and Phthalate Concentrations (n = 877)

	FR (95% CI)
Total bisphenols	0.98 (0.92–1.04)
BPA	0.99 (0.95–1.04)
BPS	0.98 (0.94–1.02)
Phthalic acid	0.96 (0.90–1.02)
LMW phthalate metabolites	0.96 (0.92–1.02)
HMW phthalate metabolites	0.98 (0.91–1.05)
DEHP metabolites	0.99 (0.92–1.06)
DNOP metabolites	0.96 (0.90–1.03)

Data analyzed using a Cox proportional hazards model (R, version 3.3.2). Increases are per natural log increase in first trimester urinary total bisphenols/BPA/BPS/phthalic acid/LMW/HMW/DEHP/DNOP metabolite concentrations. Models are fitted. All models are adjusted for maternal age, education, parity, folic acid supplement use, and urinary creatinine concentration.
