Outcome	Tracheal tube N=281	No tracheal tube N=73	OR (95% CI)	P value
Any apnea (0–12hr)	11 (4%)	4 (5%)	0.72 (0.18 to 2.85)	0.6406
Any early apnea (0–30min)	8 (3%)	4 (5%)	0.44 (0.09 to 2.08)	0.2981
Any late apnea (30min–12hr)	6 (2%)	1 (1%)	1.37 (0.06 to 30.22)	0.8413

In the GA arm 281 (79%) of infants had a tracheal tube. There were four cases where use of a tracheal tube was not recorded. There was no evidence for an association between tracheal tube and apnea in the 354 infants in the GA arm without protocol violation.
