Logistic regression analysis in patients with severe sepsis, with occurrence of IFI in the ICU as the dependent factor

Variable	OR (95% CI)	P value
Mechanical ventilation (>3 days)	3.28 (1.67–6.45)	0.001
APACHE II score	1.43 (1.17–1.76)	0.001
Coexisting infection by both Gram-positive and Gram-negative bacteria	4.06 (2.23–7.38)	<0.001
Urethral catheterization (>3 days)	3.97 (1.45–10.89)	0.007

A total of 318 patients were included in this analysis. APACHE, Acute Physiology and Chronic Health Evaluation; APS, Acute Physiology Score; CI, confidence interval; OR, odds ratio.
