Association of severe persistent acute kidney injury with the outcomes of mortality and hospital length of stay.

Mortality	Odds Ratio (95% CI)	P-value
Severe Persistent AKI (ref: transient/no AKI)	3.00 (0.74, 12.17)	0.12
CBP (every 30 min increase)	1.47 (1.05, 2.05)	0.02
Cardiac Arrest	5.03 (2.85, 8.90)	<0.0001
Center (Ref: Center-2)	0.96 (0.55, 1.69)	0.89
ICU Length of Stay
Persistent AKI (ref: transient/no AKI)	1.05 (0.75, 1.47)	0.77
CBP (every 30 min increase)	0.99 (0.93 1.06)	0.84
Cardiac Arrest	1.27 (1.08 1.50)	0.005
Center (Ref: Center-2)	1.08 (0.99 1.19)	0.09
Hospital Length of Stay	Incidence Rate Ratio (95% CI)	P-value
Severe Persistent AKI (ref: transient/no AKI)	1.11 (0.81, 1.50)	0.52
CBP (every 30 min increase)	1.05 (0.99, 1.12)	0.10
Arrest	1.20 (1.03, 1.39)	0.02
Center (Ref: Center-2)	0.95 (0.87, 1.03)	0.23
