Abbreviations: CXR = chest X-ray; ARDS = Acute Respiratory Distress Syndrome; BMI = Body Mass Index. Diagnoses are based on past medical history, and are coded as present (e.g. Pneumothorax = 1) if recorded in the electronic medical record at any time before the date of presentation for COVID-19 screening. Disorders marked by ‘*’ refer to pre-existing conditions documented in the electronic medical record.
