Diagnoses were based on past medical history and were coded as present (eg, pneumothorax = 1) if recorded in the electronic medical record at any time before the date of presentation for COVID-19 screening. All coefficients were applied to rescaled predictors, where the rescaling was done by subtracting the mean and then dividing the standard deviation in Supplementary Table 1.

Abbreviations: ARDS, acute respiratory distress syndrome; BMI, body mass index; COVID-19, coronavirus disease 2019; CXR, chest radiograph; SpO₂, oxygen saturation.
