Associations between indoor PM2.5 concentrations during pregnancy and BASC composite scores at age 2, age 4, and combined1. 1Age 2 and 4 BASC scores modeled together in a linear mixed effects model. 1st trimester IQR = 20.1 ug/m3, 2nd trimester IQR = 21.6 ug/m3, 3rd trimester IQR = 13.5 ug/m3, full pregnancy IQR = 9.63 ug/m3. Models adjusted for intervention status, maternal age at baseline, monthly family income at baseline, living with a smoker at any time during pregnancy, mother’s depression score at the 2-year visit, and maternal WASI matrix reasoning and vocabulary scores at the 2-year visit. Trimester-specific models were also adjusted for PM2.5 concentrations in other trimesters
