Unsupervised hierarchical clustering. Heatmap showing unsupervised hierarchical clustering of 187 samples using the 880 differentially methylated CpG sites obtained in differential methylation analysis (RnBeads). The blue color indicates hyper-methylation while red indicates hypo-methylation. Green bars represent “severe” COVID-19 patients. Orange bars represent “mild” patients (used as controls). Cluster analysis was performed using the “complete” clustering method and assuming Euclidean distances
