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

Figure 5

Heat map showing the relative abundances of OTUs in sputum samples from subjects with NA and non-NA. Comparisons between groups were made by using Mann–Whitney U test. Significant differences of relative abundances between groups were shown as < 0.05, < 0.01, and < 0.001. Significant differences of actual loads between groups were shown as < 0.05 and < 0.01. NA: neutrophilic asthma; Actino: Actinobacteria; Fuso: Fusobacteria; Sacch: Saccharibacteria; Spiro: Spirochaetae.
