Notes: All conventional logistic regressions clustered standard errors at the mother-level. Conventional logistic regressions sample from all children, and sibling fixed effects regressions sample only from children with in-sample siblings.
*Adjusted regressions included the following control variables: maternal characteristics at delivery (age; race/ethnicity; nativity; education; marital status; residence county urbanicity; chronic hypertension; chronic diabetes) and parity.
