a
Displays discharge status for the 1677 infants in the study. Data are reported as n (%) unless otherwise stated.
b
Outcomes for infants who survived to discharge from the CHND hospital, with available linked PHIS data, as indicated in the “PHIS linkage available” row. Subsequent outcome rows are calculated as percentage of that row as a denominator.
CHND = Children’s Hospitals Neonatal Database; PH= pulmonary hypertension; PHIS = Pediatric Hospitals Information System; IQR = inter-quartile range; PMA = postmenstrual age.
