Odds Ratios for the Association between Interstitial Lung Abnormalities and Acute Respiratory Distress Syndrome and Interstitial Lung Abnormalities and 28-Day Mortality

	Unadjusted Comparison of ILA vs. No ILA		Adjusted Comparison of ILA vs. No ILA
	OR (95% CI)	P Value	OR (95% CI)	P Value
ARDS	3.5 (1.9–6.5)	<0.0001	4.2 (2.1–8.2)	<0.0001
28-day mortality	1.8 (1.02–3.1)	0.04	2.3 (1.2–4.2)	0.01
28-day mortality (only patients with ARDS)	2.1 (0.9–4.9)	0.1	2.4 (0.9–6.5)	0.08

Definition of abbreviations: ARDS = acute respiratory distress syndrome; CI = confidence interval; ILA = interstitial lung abnormalities; OR = odds ratio.
