  1. Significance of the model p < 0.001. Final model adjusted for gestacional age, SNAPPE II respiratory distress syndrome, apnea, pulmonar hemorrhage, patente ductus arteriosus, clinical sepsis, necrotizing enterocolitis, need for oxygen therapy at 28 days of life, peri-intraventricular hemorrhage grades 3-4 (PIVH 3-4), retinopathy of prematurity, use of umbilical cateter, need for mechanical ventilation, use of parenteral nutrition, hospitalization > 60 days, and neonatal unit where the neonate was born
