PCoA (principle co-ordinates) plots showing relatedness by two established metrics, Bray Curtis dissimilarity, and UniFrac distances, while unweighted UniFrac illustrates separation between the three groups (CAC, CAS & CFS). a. Plot of principle co-ordinates using Bray-Curtis dissimilarity. Points are coloured according to group and ellipses describe the distribution of points for each group. Percentage variation explained: PCA 1 (22.3%) and PCA 2 (7.7%). b. Plot of principle co-ordinates using weighted unifrac distance. Points are coloured according to group and ellipses describe the distribution of points for each group. Percentage variation explained: PCA 1 (45%) and PCA 2 (11.7%). c. Plot of principle co-ordinates using un-weighted unifrac distance. Points are coloured according to group and ellipses describe the distribution of points for each group. Percentage variation explained: PCA 1 (16.6%) and PCA 2 (4.9%)
