Percentage relative abundance of the first 30 out of 131 genera in the estimate of the mean of the reference single Dirichlet component, 
, and the four Dirichlet mixture components, 
fitted to the Twins data. For the mixture components the upper and lower 95% credible intervals are also given in the format (lower-MPE-upper). These are calculated as the maximum posterior estimate minus/plus two standard deviations as calculated from the inverse Hessian. Genera are ranked in order of their contribution to the total mean difference of 158%, split 34%, 26%, 51% and 47% across components, and the cumulative fraction of this difference accounted for given in the last column in the table.
