Identity and relative abundances of viruses in the smoker and nonsmoker lung. Heatmap of relative abundances of the 247 viral populations based on median normalized coverage for each virome. Each row shows the viral community composition of smokers and nonsmokers, also identified by bacterial pneumotype as determined in [26, 27]. Each column represents a distinct viral population coded by host phylum, virus type, and database in which the viral genome can be found. The dendrogram above the heatmap shows hierarchical clustering of viral populations based on abundances across the different viral communities. BPT = background predominant taxa, SPT = supraglottic predominant taxa, NA = not assessed
