We identified our study population by extracting severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RT-PCR test results (positive or negative) of nasopharyngeal swabs from all consecutive patients older than 18 years analyzed at our hospital's laboratory from the ED from March 6-31, 2020, who had a CXR at presentation (within 24 hours of the first RT-PCR).
