Microbiome profile of COPD subjects based on smoking pack year history. a Relative abundance of major phyla between all COPD (n = 218) represented in the outer ring followed by ex-smokers (n = 148) in the middle ring and innermost ring representing current smokers history (n = 70). b Relative abundance of major genera between all COPD (n = 218) represented in the outer ring followed by ex- smokers (n = 148) in the middle ring and innermost ring representing current smoker (n = 70). c PCoA analysis of weighted unifrac distance measures relative to pack year history. d Alpha diversity indices comparison between the two smoking groups
