Taxonomic comparison of all DNA samples. Hierarchical clustering result of “family” level taxonomic comparisons of data from unstable atherosclerotic plaques from 15 patients with symptomatic atherosclerotic disease (unstable plaques) and stable plaques from a control group of 7 patients that died from other causes than atherosclerosis (controls). Red indicates down-regulation, green indicates up-regulation, and black indicates no change in read abundance level comparing to all samples. Hierarchical clustering was computed with average linkage, whereas Pearson correlation was used for clustering the families (rows) and Spearman correlation was used for clustering the datasets (columns), respectively
