a
A total of 42 infants in the new system group and 55 infants in the T-piece group were intubated.
b
Surfactant use in the DR included the LISA and MIST methods (12 infants in the new system group and 14 infants in the T-piece group) and INSURE method (1 infant in the new system group and 1 infant in the T-piece group). Infants receiving the INSURE method were counted as being intubated.
