Sepsis-Related Mortality of Very Low Birth Weight Brazilian Infants: The Role of Pseudomonas aeruginosa

Table 5

Risk factors for mortality and for survival in the 71VLBW infants with sepsis, identified by predictive model based on a backward step-by-step unconditional multivariate logistic regression.

	Risk Factor	OR	CI95	𝑃
Step  1(a)	Length of stay	0.933	0.900–0.967	.000
Step  2(b)	Length of stay >33 days	0.938	0.905–0.972	.000
	Birth weight ≤1000 g	13.232	2.603–67.249	.002
Step  3(c)	Mechanical ventilation	6.726	1.043–43.363	.045
	Length of stay >28 days	0.944	0.912–0.978	.001
	Birth weight ≤1000 g	9.600	1.702–54.156	.010
