- Phthalate measurements at each visit were log-transformed. All models were adjusted for specific gravity at the respective visit, time of sample collection, maternal age at first visit, race, and education. The single-pollutant models for MBzP, MBP, MiBP, MEP, and MCPP are also adjusted for health insurance provider. Bolded cells indicate significant (p < 0.05) odds ratios (OR), hazard ratios (HR), and percent changes (% Change). Odds ratios, hazard ratios and percent changes are all calculated on IQR (Interquartile Range) scale.
