#p-value for the radiological sign.

Odds ratios indicate the associations of the radiological variables at follow-up with severe/critical disease. E.g. the odds of severe/critical disease is 11.7 times higher for a patient with than for a patient without hypoattenuation, adjusting for age and sex.

Abbreviations: CI: confidence interval; COVID-19: coronavirus disease 2019; DLCO: diffusing capacity of the lung for carbon monoxide, OR: odds ratio.
