Cluster Analysis of COVpos and COVneg cases by SARS-CoV-2 status and Marker Scores. In this cluster analysis, subjects are clustered by similarity in marker scores and COVID-19 status. The large red, blue and orange bar on the y-axis refers to the COVID status: Red bar = subjects whose COD was SARS-COV-2 disease (COVID-19). Orange bar = subjects who were positive for SARS-COV-2 at postmortem examination but whose primary COD was not COVID-19. Blue bars = subjects who were negative for SARS-CoV-2 at postmortem examination. Marker names are on the X axis. Marker grades are displayed as various colors. Pale yellow = no staining (grade 0). Bright yellow = minimal staining (grade 1). Orange = moderate staining (grade 2). Brown = large amounts of staining (grade 3). LV = left ventricle; RV = right ventricle
