Table shows the results from multivariable linear regression analyses between prenatal ambient air pollution exposure and cognitive outcomes assessed at 2 years in Latino infants. Models adjusted for socioeconomic status (SES), breast feedings per day, gestational age, pre-pregnancy BMI, infant birthweight, and infant sex. Table shows 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 PM_2.5 = 1.24 µg/m³). Statistical significance is denoted in bold (p < 0.05) while * and ** represent an adjusted p-value of p < 0.10 and p < 0.05 respectively
