Table 4. Effect of OVS on associated comorbidities in a multivariable logistic regression model.

Variable	OR [95% CI]	P value
Hyperlipidemia	0.91 [0.82; 1.01]	0.0722
Hypertension	0.98 [0.89; 1.09]	0.7502
Stroke	1.07 [0.84; 1.36]	0.5925
Coronary artery disease and myocardial infarction	1.1 [0.95; 1.28]	0.2115
Peripheral arteriopathy	1.91 [1.52; 2.4]	<0.0001
Heart failure	1.27 [0.99; 1.62]	0.0644

*Odds ratio (OR) is the effect of overlap syndrome (OVS) on different cardiovascular comorbidities after adjustment for age, gender, body mass index, exposure to cigarette smoke, the apnea-hypopnea index and the type of sleep study (type III or type I).
