| an = 648 subjects and 2,693 urine samples (reduced sample size due to missing BMI and SG values). bExponentiated adjusted parameter estimates from multivariate regression models (including sex, race, and BMI) are presented due to natural log transformation of the outcome and can be interpreted as a relative (times) change from the reference category of the predictor variable; each paraben is modeled separately. | ||||||
