Table 3. Univariate and multivariate logistic regression models with the dependent variable ‘signs of pneumonia’.

Independent variable	Cohort	Odds ratio (95% interval)	p-value
Overweight/obese vs. lean	PCR (n = 165)	2.68 (1.29–5.59)	0.008
BMI as metric variable	PCR (n = 165)	1.083 (1.014–1.155) per 1 kg/m2	0.017
Overweight/obese vs. lean	PCR + AB (n = 201)	2.32 (1.16–4.64)	0.017
Overweight/obese vs. lean with adjustment for age group, sex, pulmonary and psychiatric disease	PCR (n = 165)	2.33 (1.06–5.12)	0.036

PCR: participants with a diagnosis of SARS-CoV-2 infection by PCR.

AB: participants with a retrospective diagnosis by antibody testing.
