Discuss Changes in gut microbiota composition and diversity associated with post-cholecystectomy diarrhea

Alpha diversity was not carried out in this study. The only mention of alpha diversity (in the methods section under "Sequencing data analysis and statistical analysis") says "Phylogenetic diversity tree diversity indices were used to assess the α-diversity, which represents the species abundance in a single sample". The observed diversity in terms of community richness between controls and PCD group was also not significant (under "Diversity and richness of gut microbiota decreased after cholecystectomy", lines 6&7). This is why there is no alpha diversity results curated.
