From: Microbial burden and viral exacerbations in a longitudinal multicenter COPD cohort
Longitudinal variations of the COPD sputum microbiota at stable state is associated with higher disease burden. a Longitudinal Taxa barplot at Genus level of all 42 patients representing the top (variable) and bottom (consistent) quartile of median weighted UniFrac distances at stable states. b Proportions of patients with low or high longitudinal microbiota variability associated with geography, and boxplots with interquantile range whiskers for the frequency of exacerbations, and of viral infections
