The correlation between the diagnosis on discharge and the final diagnosis based on the PCR results and the multidisciplinary diagnosis. The panels on the left side indicate the diagnosis at discharge, and those on the right side indicate the final diagnosis based on the PCR results and the multidisciplinary diagnosis. The patients with a final diagnosis of viral pneumonia were diagnosed on discharge as having cryptogenic organizing pneumonia (COP), chronic eosinophilic pneumonia (CEP) or acute fibrinous organizing pneumonia (AFOP) (n=22), acute interstitial pneumonia (AIP) (n=5), connective tissue disease (CTD) -related interstitial lung disease (ILD) (n=3), unclassified interstitial pneumonia (n=2), pneumonia (n=20), and drug-induced ILD (DILD) (n=1).
