Multivariate binary logistic regression models for Acute Kidney Injury (No-AKI vs. AKI [R, I or F]) morbidity and mortality prediction in PICU (Pediatric Intensive Care Unit)

	AKI† OR (95% CI)
Outcome variables	Unadjusted	Age-adjusted	Age, fluid overload, PRISM II score
Mortality	2.12 (0.85–5.27)	2.61 (0.96–7.09)	1.94 (0.62–6.12)
LOS Hospital (≥20 days)	1.89 (1.07–3.32)	1.64 (0.89–3.00)	1.21 (0.62–2.34)
LOS PICU (≥15 days)	3.73 (1.89–7.38)	2.93 (1.40–6.12)	2.11 (0.91–4.86)

AKI: acute kidney injury (R,I or F);

^†Reference category: No-AKI ; OR: odds ratio; CI: confidence interval; fluid overload (≥10%), PRISM II score (≥10)
