Figure 2. Kaplan-Meier Plot of Cumulative Events for the First 72 Hours.

Figure 2.

Events are defined as delivery room intubations and deaths followed by mechanical ventilation or deaths in the neonatal intensive care unit. Intubations for the INSURE method or catheter delivery of surfactant in the neonatal intensive care unit (without mechanical ventilation) were not included. All infants who died in the neonatal intensive care unit were intubated. There were no missing values and no infants lost to follow-up. Log-rank test at 30 minutes and 72 hours were not statistically significant.
