Total ventilation (days) includes nasal CPAP and invasive ventilation. Early onset sepsis refers to sepsis presenting in the first 72 h of life. Late onset sepsis refers to sepsis presenting after 72 h of life. Outcome score is a calculated score between 0 and 6, based on six parameters (mortality, BPD, NEC, ROP stages 2–4, PVH/IVH grades 3–4, PVL) with a weighted value of 0–1. BPD bronchopulmonary dysplasia, CPAP continuous positive airway pressure, LOS length of stay (hospitalization days), NEC – necrotizing enterocolitis, PVH/IVH periventricular/intraventricular hemorrhage grade 3–4, PVL periventricular leukomalacia, RDS respiratory distress syndrome, ROP retinopathy of prematurity stages 2–4, SD standard deviation, SRT surfactant replacement therapy
