A total of 287 neonates were included. Each additional week of GA at birth led to a 1.53 increase in the odds of successful extubation (95% CI 1.122-2.096, p<0.01). Higher average fraction of inspired oxygen (FiO2) requirements in the preceding 24 hours resulted in a 0.94 decrease in the odds of successful extubation (p<0.05) and higher mean airway pressure (MAP) resulted in 0.76 decrease in odds of successful extubation (p<0.01).
