Table 3.

Multivariable model for hospital mortality

Patient characteristics	Adjusted odds ratio (95%CI)
Diuretics, 48–72 h after ARDS	0.46 (0.22, 0.96)
Age, categorized	1.83 (1.14, 2.95)
Congestive heart failure	0.59 (0.26, 1.34)
Trauma as ARDS risk factor	0.52 (0.22, 1.24)
SOFA score, at ARDS onset, categorized	6.35 (1.91, 21.13)
Volume overload at 48 h	1.65 (0.74, 3.71)

Age at admission was categorized into groups of <55, 55–70, 70–80, >80 years old.

SOFA score was categorized into groups of ≤8, >8 and ≤ 16, and >16 for a linear association with mortality

Volume overload is defined as a net ICU fluid balance (in L) equivalent to more than 10% of admission body weight (in kg)
