Results of multivariable logistic regression model to determine significant predictors for ICU admission and in-hospital death among 228 patients with viral pneumonia admitted to the studied hospitals during the COVID-19 outbreak in Tehran, Iran. SE= standard error; OR= odds ratio; CI= confidence interval

Outcome	Variables	Beta (estimate)	SE	P value	Adjusted OR	95% CI
In-hospital death	Age (per 1 year increase)	0.06	0.01	< 0.001	1.06	1.03 to 1.10
	Total CT score (per 1 score increase)	0.10	0.05	0.03	1.10	1.00 to 1.22
	Blood oxygen saturation < 88%	− 0.52	0.24	0.03	2.88	1.09 to 7.62
	Intercept	− 6.77	1.41	< 0.001
ICU admission	Age (per 1 year increase)	0.05	0.01	< 0.001	1.05	1.02 to 1.09
	Total CT score (per 1 score increase)	0.12	0.04	0.008	1.13	1.02 to 1.24
	Blood oxygen saturation < 88%	− 0.68	0.22	0.002	3.97	1.61 to 9.74
	Intercept	− 5.83	1.26	< 0.001
