	Regression coefficient	Wald	P	Exp (B)	95% CI for Exp (B)
AHI	0.05	5.45	0.02	1.05	1.01-1.1
Smoking	3.48	10.40	0.001	32.37	3.9-268
Age	0.15	6.53	0.011	1.16	1.04-1.29
Intraoperative blood transfusion	0.44	4.43	0.04	1.55	1.03-2.32

Albumin	−0.12	1.29	0.26	0.89	0.72-1.09

(Exp (B) describes the change in odds ratio for each unit change of the independent variable). AHI, apnea-hypopnea index; CI, confidence interval.
