Table 5

Multivariate analysis of predictors of hospital mortality in patients with severe acute respiratory failure.

Variables	Odds ratio	CI	𝑃 values
SOFA* score	1.27	1.04–1.55	0.02
PaO2^∗/FiO2^∗ day 3	1.01	1.00–1.02	0.05
OI* day 3	1.49	1.13–1.95	0.004
OI change from day 1 to day 3	1.11	0.99–1.24	0.07

 *FiO₂: fraction inspired oxygen, OI: oxygenation index, PaO₂: arterial oxygen tension, SOFA: Sequential Organ Failure Assessment.
