Alternations in the gut microbiota of patients with silicosis compared with healthy subjects. a, c Rarefaction curves comparing the species richness (observed OTUs) and overall diversity (Shannon–Wiener index). The curves indicated a lower diversityin the gut microbiota of patients with silicosis and lung fibrosis. b OUT number distribution in control and case group, respectively. d relative abundance(%) of bacteria in phylum level in two groups
