Neutrophilic Asthma Is Associated with Increased Airway Bacterial Burden and Disordered Community Composition

Figure 3

Bacterial community distributions in sputum samples from subjects with NA and non-NA.  β-Diversity grouped by sputum neutrophil percentage was evaluated by NMDS based on Bray Curtis distance. Comparison between two groups was made by using a PERMANOVA test (Adonis). Each dot represents the overall bacterial community in each sample. NA: neutrophilic asthma; NMDS: nonmetric multidimensional scaling.
