Summary of the results of the unadjusted and adjusted logistic regression cox proportional regression model assessing the association between undiagnosed sleep disorder breathing and COVID-19 outcomes.

Variable	Unadjusted (95%, CI)	p-value	Adjusted (95%, CI)	p-value
Risk of ARDS	6.17 (1.96–19.43)a	< 0.01	6.72 (1.56–28.93)ac	< 0.01
Impairment Chest CT	5.79 (2.07–16.17)b	< 0.01	17.29 (1.68–177.45)bd	0.01
Impairment DLCOc	0.874 (0.31–2.46)b	0.80	1.16 (0.27–4.95)bd	0.84

Definition of abbreviations: ARDS: Acute respiratory distress syndrome; CT: Computed tomography; DLCO: Diffusing capacity of the lungs for carbon monoxide corrected by hemoglobin; CI: Confidence interval; Highlights: Statistically significance with a p-value<0.05.

^aValues expressed as Odds ratios.

^bvalues expressed as Hazard ratios.

^cLogistic regression model adjusted by age, sex, hypertension, BMI, smoking status, ferritin levels, and D-dimer levels at baseline.

^dCox proportional hazard model adjusted by Age, gender, hypertension, BMI, smoking status, ARDS, awake vigil prone positioning, steroid usage, IMV, NMB, tracheotomy, and days on IMV), total time with oxyhemoglobin saturation below 90%, Oxygen desaturation index 3%, lowest SpO2.
