Table 3 Summary of significant prognostic factors’ characteristics identified in the multivariate analysis

Parameter	Odds ratio	95% Wald confidence interval
Number of RRT treat.	5.1	1.65	16
Hospitalization length	0.4	0.2	0.7

Parameter	Odds ratio	Sensitivity (%)	Specificity (%)	AUC	Cut-off
UOP (day 3)	0.2	76.9	90	0.9	1 mL/kg/h
K (day 2)	1.9	53	90	0.7	5.3 mmol/L
DeltaCreat/h (1–2)	1.2	92	63	0.8	1.83 µmol/L/h

Number of RRT treat.: number of extracorporeal renal replacement therapy (RRT) treatments. UOP (day 3): median urinary output at day 3. K (day 2): serum potassium concentration at day 2. DeltaCreat/h (1–2): difference between serum creatinine concentration in µmol/L/h after the first and before the second RRT treatment divided by the time (in hours) between the 2 treatments
