Methods
We studied a retrospective cohort of neonates
(23+0-29+6 weeks GA), with evidence
of BPD, prescribed their first course of systemic dexamethasone to aid
in extubation from mechanical ventilation. The data collected only
pertained to the first course of dexamethasone for any given neonate,
with the primary outcome of interest of successful extubation within 14
days (i.e., extubated within 14 days of starting dexamethasone and
remaining extubated for at least seven days). Binary logistic regression
was employed.
