Association between asthma and hospitalization for COVID-19

	Model 1 (N=1,252)	Model 2 (N=857)	Model 3 (N=1,252)
Asthma	3.95 (1.43-10.9) **	4.87 (1.44-16.43) **	3.33 (1.19-9.33) *
Age, years	0.88 (0.82-0.95) **	0.91 (0.83-1.01)	0.91 (0.85-0.98) *
Male sex	0.55 (0.24-1.26)	0.42 (0.14-1.27)	0.49 (0.21-1.15)
Race: - White - Black - Other/unknown	Ref. 3.00 (1.28-7.07)* 0.54 (0.07-4.23)	Ref. 1.41 (0.35-5.71) 2.69 (0.30-24.3)	Ref. 4.55 (1.87-11.1)* 0.51 (0.06-4.18)
Recent travel	1.39 (0.52-3.68)	2.79 (0.29-26.5)	1.34 (0.40-4.52)
Known exposure	0.27 (0.52-0.62) **
Low zip code income		2.54 (0.75-8.58)
BMI, percentile		1.01 (0.99-1.03)
Days from symptom onset to presentation		1.002 (0.99-1.01)
Initial symptoms: - Fever - Fatigue - Vomiting			1.90 (0.40-4.52) 3.15 (1.23-8.09)* 8.62 (3.15-23.6)**

Numbers shown are odds ratios (95% confidence intervals) for hospitalization. All models adjusted for age, sex, race, recent travel, and known exposure. Model 2 additionally adjusted for zip code’s median household income, BMI percentile, and the time interval (days) between symptom onset and presentation; these were not included in Model 1 because of greater missingness (~30% were missing BMI or time interval data, thus N=873). Model 3 additionally adjusted for non-asthma related symptoms that were significant in the unadjusted analysis (fever, fatigue, and vomiting; see Supplementary Table S1).
