From: Lung histopathologic clusters in severe COVID-19: a link between clinical picture and tissue damage
Cluster analysis. A The dendrogram of hierarchical clustering. Patients with clinical data are labeled in black at the bottom of the dendrogram. B The characteristics of histopathologic patterns according to the clustering. On the left, the color scale according to the semiquantitative histopathologic assessment is shown. Only two patients of cluster 4 and none of cluster 5 had clinical data. Overall, patients with no clinical data (n = 27) had a short LOS in hospital because three died at home and six shortly after emergency department access. Moreover, only nine of them (33.3%) were admitted to ICU and underwent mechanical ventilation. Cluster labels are indicated by the circled numbers
