Annals of Intensive Care

Table 2 Factors associated with survival censored at day 28 (Cox Model) and risk of AKI (logistic regression)

	Estimate	95% CI	p value
Model 1 (survival censored at day 28)	Hazard ratio
Modified SOFA score at admission (per point)	1.23	1.04–1.45	0.01
Acute Kidney Injury	3.08	1.12–8.45	0.03
Model 2 (acute kidney injury)	Odds ratio
Chronic kidney disease	3.91	0.97–26.20	0.09
Modified SOFA score at admission (per point)	1.29	1.04–1.70	0.04

Model selection was performed according to forward variable selection conditioned on p value (critical entry p value < 0.2, critical exit p value < 0.1)
