Clustering of microbiota taxonomical profiles. A Hierarchical clustering on multiple factor analysis of the microbiota profile of individuals at different visits. Variables contributing to the difference between the clusters are displayed on the dendrogram. Horizontal colored bar below the dendrogram represents the visit associated with sample. B Barplot showing the relative abundance of the 16 more abundant microbiota genera. Microbiota alpha diversity measured on all sequence variants by Simpson’s index (1-D) between C microbiota clusters and D bioactive lipid clusters
