Dendrogram from hierarchical clustering analysis of COVID-19 cumulative incidence, maximum daily ICU occupancy, and mortality data of Italian regions, as in Table 1, (left); and map of the Italian regions of the two groups’ G_HC of the dendrogram (right). The regions of group 1 (high values of cumulative incidence, maximum daily ICU occupancy and mortality) are plotted in gray. The regions in dark gray also belong to group 1 G_IC. Liguria and Emilia Romagna, in light gray, belong to group 1 G_HC, but not to group 1 G_IC.
