Study characteristics
Methods	Single center double‐blind randomized trial on moderate‐ versus low‐dosage regimen of dexamethasone.
Participants	Extremely low birth weight infants (≤ 1500 grams), initial starting administration between 7 and 21 days.
Interventions	The included infants were randomly assigned to 1 of 2 dosage regimens. A moderate‐dosage regimen with an unknown cumulative dose of dexamethasone administered over a 7‐day course, starting with 0.5 mg/kg/day, and then tapered during 7 days with unknown schedule. A low‐dosage regimen with a cumulative dose of 0.7 mg/kg administered over 7 days: 0.1 mg/kg/day for 7 days
Outcomes	Primary outcomes were growth parameters (weight, length and head circumference) at 36 weeks' corrected gestational age. Secondary outcomes were documented sepsis and long‐term growth parameters at 9 months of corrected age (actual numbers not provided).
Notes	Funding: no statement. Declarations of interest: not reported. Trial was only published as an abstract and original authors could not provide any additional data.
