Table 4 Multivariate logistic binary regression analysis of the cardiac patients' odds of prolonged aortic cross-clamp time (N = 609)

	Multivariate adjusted odds ratio	95% CI for OR		p value
	Multivariate adjusted odds ratio	Lower	Upper	p value
Sex = male	0.718	0.460	1.120	0.144
Age > 65 years	1.717	0.991	2.974	0.054
Smoker = yes	1.889	1.301	2.743	0.001
Body mass type: obese or overweight	1.764	1.182	2.631	0.005
A positive history of respiratory illness	0.484	0.243	0.964	0.039
Underwent AVR surgery = Yes	2.117	1.170	3.829	0.013
EUROSCORE	1.026	0.792	1.330	0.844
Constant	0.435			0.003

Dependent variables = aortic cross-clamp time > 51 min. Model overall statistical significance χ²(7) = 30.81, p < 0.001. Model AUC/ROC = 0.70
