Multivariate analysis of variables with adjusted odds ratio predicting mortality

Variable	Adjusted odds ratio (95% CI)	p-value
Severe ARDS	7.6 (0.59–98)	0.119
Steroid use	0.9 (0.19–4.9)	0.96
RRT	4.2 (0.76–23)	0.09
MODS	0.47 (0.08–2.70)	0.4
PRISM III	1.2 (1.03–1.5)	0.021*
P/F ratio	0.94 (0.92–0.95)	0.000*
OI	2.54 (2.08–3.0)	0.000*
MAP	1.7 (1.4–2.1)	0.000*

^*p-value <0.05 is significant;

CI, confidence interval; MAP, mean airway pressure; MODS, multiorgan dysfunction syndrome; OI, oxygenation index; P/F, PaO₂/fractional oxygen concentration in inspired air; PRBC, packed red blood cell; PRISM, pediatric risk of mortality; RRT, renal replacement therapy
