Fig. 5From: Association of exacerbation phenotype with the sputum microbiome in chronic obstructive pulmonary disease patients during the clinically stable stateCorrelation between the sputum microbiome and lung function in stable COPD. a Spearman correlations between the relative abundances of bacteria and the values of post-BD FEV1/FVC were calculated and plotted. b Proteobacteria and Neisseria show negative correlations with the values of post-BD FEV1/FVC. c The association of the Chao1 and Shannon indices and the values of post-BD FEV1/FVC. Bonferroni-adjusted p-values < 0.05/27 (5 phyla, 20 genera, 2 diversity indices) = 0.0019 indicate significanceBack to article page
