Hospital rates of antenatal corticosteroid use among resuscitated infants were included as a continuous variable in the hospital level of the models. At the individual level, models were adjusted for birth weight (grams), sex, plurality of birth (singleton versus multiple) and the mother’s age (≤19 years versus >19 years), race (white, black, or other), ethnicity (Hispanic versus non-Hispanic), enrollment in private health insurance (yes versus no), receipt of prenatal care (≥1 visit versus no visits), hypertension during pregnancy (yes versus no), insulin-dependent diabetes (yes versus no), and clinical chorioamnionitis (yes versus no).
