^aOutcomes were measured by the Bailey Scales of Infant and Toddler Development- 3rd Edition and adjusted for corrected age.
^bAdjusted odds ratios were calculated using multivariable ordinal cumulative probability regression models and adjusted for the following variables: birth weight, inborn status, antenatal steroid receipt, race, high frequency ventilation use, intraventricular hemorrhage, periventricular leukomalacia, and necrotizing enterocolitis, and sex.
