Clinical utility of chest radiography for severe COVID-19

Abstract

Adjusting for key confounders of age and baseline Hb, CRS_max performed comparable to or better than laboratory markers in the diagnosis of severe disease. CXR performed between the 6^th and 10^th days from symptom onset was a better predictor of severe disease than CXR performed earlier at presentation. A benign clinical course was seen in CXR that were normal or had very mild abnormalities.
