The risk for bloodstream infections is associated with increased parenteral caloric intake in patients receiving parenteral nutrition

Table 4 Multivariate analysis of factors associated with bloodstream infection risk

Variable	Adjusted odds ratio	P value	95% confidence interval
Male sex	1.6	0.13	0.8–3.1
Intensive care unit location	3.2	0.001	1.7–6.2
Maximum parenteral calories	1.6	0.002	1.2–2.1

Data from forward stepwise logistic regression. In this analysis, maximum parenteral nutrition calories per kilogram (adjusted weight for patients with body mass index ≥ 30 kg/m²) are categorized into four groups (quartiles): ≤ 25 kcal/kg, 26–34 kcal/kg, 24–39 kcal/kg, ≥ 40 kcal/kg.
