Multivariable model with McGill oximetry score and age.

	PRAE n/N (%)	Univariable Odds Ratio (95% CI)	P	Multivariable Odds Ratio (95% CI)	P
McGill oximetry score		1.49 (0.90, 2.50)	.12	1.43 (0.83, 2.46)	.19
Age category (years)			.19		.26
≥ 6	6/57 (10.5)	1.00 (ref)		1.00 (ref)
3 to 5	6/41 (14.6)	1.46 (0.42, 5.02)		1.29 (0.36, 4.52)
< 3	3/8 (37.5)	5.10 (0.88, 27.02)		4.30 (0.72, 23.23)

The area under the receiver operating characteristic curve is 0.68 (95% CI: 0.52, 0.84). CI = confidence interval, PRAE = perioperative respiratory adverse event, ref = reference.
