PCoA plot showing the differences in the samples. a Samples plotted on PCoA 1 and 2, percentage of explained variation is given in the legends. Each color represents an individual, the larger and less opaque spheres are gluten-free diet time points, and the smaller spheres in the same color are habitual diet time points. b The differences in the first component over the time points. There are two groups based on richness, i.e. high versus low, one individual had samples in both groups. The sample belonging to both richness groups has a bolder color
