↵Demographics and clinical results between modes of delivery.
*p<0.05. By 2 hours after birth, all infants had SpO₂ ≥93% and five had a RR 70–80. By 4 hours after delivery, one infant had a RR >70 (=72).
bpm, beats per minute; CS, caesarean section; GA, gestational age; HR, heart rate; RR, respiratory rate.
