Alpha diversity analysis of microbial communities in exosomes of patients with acute and chronic cholecystitis. A The rarefaction curve. B Venn diagram showing the distribution of OTUs in the Acute and Chronic groups. C Box plot depicting the number of observed species (Observed_species index). D Abundance-based Coverage Estimator (ACE) used to estimate the number of unobserved species and calculate the estimation of the total species count. E Shannon index reflecting species richness and evenness. F Simpson index measuring species diversity and evenness within the community. **P < 0.01. ns, no significant difference. A: Acute group; B: Chronic group
