Adjusted least square mean phthalate metabolite concentrations by weight -score growth trajectory groupings. Effect estimates were calculated using linear models adjusted for maternal age (y), race (White/Black/Other), education level (High school or less/Any technical school or college/Graduate work), prepregnancy BMI (), and study site (UCSF/UMN/URMC/UW). Least square mean values are presented numerically in Table S23. Note: BMI, body mass index; MBP, mono--butyl phthalate; MBzP, monobenzyl phthalate; MCNP, monocarboxy-isononyl phthalate; MCOP, monocarboxyoctyl phthalate; MCPP, mono(3-carboxypropyl) phthalate; MEP, mono-ethyl phthalate; MiBP, mono-isobutyl phthalate; DEHP, di-2-ethylhexyl phthalate; UCSF, University of California, San Francisco; UMN, University of Minnesota; URMC, University of Rochester Medical Center; UW, University of Washington.
