	All patients: median (95% CI)	Group A: median (95% CI)	Group B: median (95% CI)
As per continuous monitoring
Below safe range	1.5% (1.0 to 2.3)	2.7% (1.7 to 5.6)	0.9% (0.3 to 1.4)
Within safe range	96.2% (83.9 to 98.5)	19.3% (16.2 to 24.3)	99.1% (98.5 to 99.5)
Within target range	92.5% (78.5 to 96.3)	15.7% (13.3 to 18.9)	97.3% (96.4 to 98.7)
Above target range	N/A	75.0% (63.6 to 81.1)	N/A
As per nurses’ record of intermittent monitoring
Below safe range	7.3%	16.0%	3.6%
Within safe range	79.3%	45.8%	96.4%
Within target range	73.1%	33.2%	92.8%
Above target range	N/A	38.2%	N/A

Group A: preterm/low birthweight neonates on oxygen (target range 90%–95%; safe range 85%–95%). Group B: term neonates, and any neonates not on oxygen (target range 90%–100%; safe range 85%–100%).
