Multivariable analysis of factors associated with ESBL-PE pneumonia among 111 patients with ESBL-PE colonization

Associated factors	AOR	95% CI	p
SAPS2 > 43	2.81	1.16–6.79	0.022
>2 days amoxicillin/clavulanic acid in ICU	0.24	0.08–0.71	0.010
Colonization with E.cloacae or K. pneumoniae	10.96	2.93–41.0	<0.0001

The multivariable model showed a good calibration as assessed by the Hosmer and Lemeshow goodness-of-fit test (χ ² = 4.9, p = 0.30) and a fair discrimination as assessed by the receiver operating characteristics curve (area under the curve = 0.80)
