Multivariable logistic regression analysis.

Variable	OR	95 % C.I.	p-value
Tiredness	0.61	0.33–1.09	0.09
Age > 50 years	0.20	0.04–0.70	0.02
Neck circumference > 40 cm	0.65	0.34–1.25	0.19
Visceral fat percentage	1.08	0.99–1.17	0.07
AHI	1.02	0.99–1.05	0.15
OSAS (medical history)	0.24	0.07–0.70	0.01
COPD	0.25	0.05–0.94	0.05
Anaesthesia duration	1.01	1.00–1.01	0.02

All factors with a p-value of < 0,30were used for the multiple logistic regression analyses. The model should be sensitive for factors associated with respiratory complications. AUROC 0.72, 95 % CI: 0.65–0.78.
