Additional file 3 of The diet rapidly and differentially affects the gut microbiota and host lipid mediators in a healthy population

Additional file 3: Figure S3. Multiple factor analysis (MFA) on microbiota profile. A) Loading plot representing the contribution of taxonomic ranks of the gut microbiota to the variability between individuals at different visits. Taxa representing less than 1% in every sample have been filtered out. The ellipses represent the 95% confidence interval of the mean of points as computed with the FactoMineR package for the effect of B) diet, C) participants and D) the five clusters of samples distinguished from hierarchical clustering of the PCA. A sixth cluster containing only two samples was excluded from cluster analysis. Barplot representing the contribution of the top 15 variables to the MFA for E) dimension 1 and F) dimension 2.
