Table 4. Multivariable analysis of the change in heart rate during intubation following fall in peripheral oxygen saturation (SpO₂) and after the use of atropine (corrected by the propensity score [PS]). Neonates are ≤28 days and older children >28 days and less than 8 years.

	Neonates (n = 153)			Older children (n = 111)
	Heart rate change (bpm)	P	CI 95%	Heart rate change (bpm)	p	CI 95%
Fall in SpO₂ by 10% points	−4.1	0.005	−1.3, −7.0	−5.4	<0.001	−2.6, −8.4
Difference with and without atropine (PS corrected)	−45.9	<0.001	−34.3, −57.5	−43.5	<0.001	−25.5, −61.5
