Beta diversity analysis. (a) Principal coordinate analysis (PCoA) scatter plot. Circles represent the 95% normal probability ellipse for each group. The pink one was on behalf of the children group and the blue one was on behalf of the newborn group. (b) The hierarchical clustering tree based on Bray–Curtis and built with the Unweighted Pair-group Method with Arithmetic averages (UPGMA).
