Odds ratios adjust for birth year (matching variable)
Models adjusted for maternal race/ethnicity, birth year, parity, maternal birthplace, and neighborhood socioeconomic index.
Control sample sizes differ because ALL models included children living within 2km of an air monitor while AML models included children living within 6km of an air monitor.
