  1. P-value< 0.05 and FDR P-value< 0.05 are shown in bold. aThe relative abundances were calculated from the original counts (number of sequences in the OTU table). bFold changes were calculated from the GLM, which corrects for differences in library size between the samples and the effects of confounding factors. It is therefore not possible to derive these fold changes from the original counts (number of sequences in the OTU table) by simple algebraic calculations
