Odds ratio and 95% confidence interval of traffic exposures and identified NNNS phenotypes. Road: road density exposure (103m/km2); VMT: VMT density exposure (104 vehicle-mile/km2). P1: profile 1; P2: profile 2; P3: profile 3. ORs and 95% CIs were calculated using multinomial logistic regression. Covariates: gender, gestational age at birth, birth weight z-score, postmenstrual age at NNNS assessment (PMA), delivery type, insurance type, neighborhood SES z-score, race, ethnicity, maternal smoking status, NICU morbidity, and base deficit at birth.
