Relationships between volume overload upon ICU discharge and inability to ambulate upon hospital discharge as estimated by multivariable logistic regression

Exposure Variable	Odds Ratio	95% Confidence Interval	P Value
Volume overload	2.29	1.24–4.25	0.01
Age (decades)	1.49	1.22–1.82	<0.01
Male	0.69	0.38–1.25	0.22
APACHE II score	1.02	0.97–1.06	0.45
Mechanical ventilation	0.71	0.33–1.51	0.37
Duration of shock (d)	1.01	0.84–1.21	0.95
Vasopressors	1.8	0.9–3.57	0.1

Definition of abbreviations: APACHE II = Acute Physiology and Chronic Health Evaluation II; ICU = intensive care unit.
