Binary (enter) logistic regression analysis was used.
Dependent variable: surfactant administration, necessitating mechanical ventilation, PDA, IVH.
Independent variables: IVF, gestational age, SGA, pPROM, preclampcia, Apgar score at 5 minutes, duration of surfactant administration, multiple gestations.
IVF, in vitro fertilization; IVH, intraventricular hemorrhage; pPROM, preterm premature rupture of membrane; SGA, small for gestational age.
