Variation in faecal microbiota and metabolite profiles in faecal samples of healthy subjects collected over three consecutive days. (A) The PCoA plot visualises the microbiota variation between the three consecutive timepoints per subject the beta-diversity was calculated using Weighted UniFrac. (B) The PCA scores plot based on all metabolites measured in both positive and negative ionization modes. The 95% confidence ellipses are shown, coloured according to the ten individuals. PCA: Principal Component Analysis, PCoA: Principal Coordinate Analysis.
