- Beta coefficients and 95% confidence intervals are shown for a one standard deviation increase in exposure (PM2.5 [SD = 1.15 μg/m3], PM10 [SD = 3.54 μg/m3], NO2 [SD = 2.34 ppb], O3 [SD = 2.38 ppb], Oxwt [SD = 1.04]) via multivariable linear regression. Results are reported for females and males with the corresponding p-value for the interaction between Oxwt and infant sex. All stratified models adjusted for infant age, pre-pregnancy BMI, breastfeeding frequency, maternal age, and socioeconomic status
