Risk factors for deconditioning and intensive care unit associated weakness (ICUAW) in patients with COVID-19 in comparison with those with viral pneumonia (3)

Risk factor for deconditioning/ICUAW	COVID-19 (n = 10,557)	Viral pneumonia, 2017 to 2019 (n = 5,782)
Duration of advanced respiratory support, median days (IQR)	13 (7–23)	9 (4–17)
Multi-organ failure, %	40.8	26.3
Age, mean (SD)	58.8 (12.7)	58 (17.4)
Very severe comorbidities, %	13.6	24
Dependency prior to hospital admission, %	10.3	26.4
