  1. Per cluster the abundance of the species percentage is shown (p ≤ 0.02). The p-value is defined as the probability of observing a K-W rank sum of the size reported or more extreme when the null hypothesis is true (null hypothesis is that the distribution equal over all clusters for the selected species or bacterial Family). The K-W rank sum expresses the deviation from the distribution under the null hypothesis. For each cluster the most dominant species was printed in boldface. Values expressed as percentage and were rounded to two significant digits
  2. a Sneathia sanguinegens could not be unambiguously discriminated from Leptotrichia amnionii
