The final multivariable logistic regression model indicated that the risk factors for death were: less than 2 doses of antenatal dexamethasone (OR = 2.5; 95% CI: 1.0 - 6.0; p < 0.05), birth weight < 1000 g (OR = 3.5; 95% CI: 1.4 - 8.5; p < 0.05), gestational age < 28 weeks (OR = 4.2; 95% CI: 1.5 - 11.8; p < 0.05), pulmonary hemorrhage (OR = 5.3; 95% CI: 1.9 - 14.9; p < 0.05), severe asphyxia (OR = 4.7; 95% CI: 1.2 - 18.0; p < 0.05) and septic shock (OR = 6.2; 95% CI: 1.9 - 20.3; p < 0.05).
