Associations Between Prenatal PM10 Exposure and Composite Cognitive, Motor, and Language Scores at 2 Years. Average prenatal exposure to PM10 (µg/m3) was inversely associated with composite cognitive score (A), composite motor score (B), and composite language score (C). Unadjusted plots and regression lines for neurodevelopmental scores and prenatal PM10 are shown. Figures show betas (β) and 95% confidence intervals (CIs) that were scaled to a 1SD difference in exposure (SD NO2 = 2.43 ppb, SD PM10 = 3.94 µg/m3, SD PM2.5 = 1.24 µg/m3) from multivariable linear regression models that adjusted for socioeconomic status (SES), breast feedings per day, gestational age, pre-pregnancy BMI, infant birthweight, and infant sex
