Authors’ analysis of hospital discharge data, 2001–2014.
ORs are computed using logistic regressions. In the adjusted regressions, we include as covariates a set of indicators for the age of the mother, dummies that identify county of residence of the mother and year dummies. SEs in the adjusted regression are clustered at the county level.
