Fig. 1.

Differently abundant taxa in CHD patients according to the sex, based on LEfSe analysis. The colors represent the group in which the indicated taxa are more abundant compared to the other group. In a taxonomic cladogram, each successive circle represents a different phylogenetic level. A Cladogram: the order from the center to the outside is phylum, class, family and genus levels. Differing taxa are listed on the right side of the cladogram. B Linear discriminant analysis. The most differently abundant taxa between sexes are represented in a bar graph according to the LDA score (log 10), an estimation of the effect size. Only taxa meeting a P < 0.05 and LDA score significant threshold |> 2| are shown. g_UBA1819: g_UBA1819 (Ruminococcaceae); g_Incertae Sedis: Ruminococcaceae incertae sedis; f_UCG_010: f_UCG_010 (Oscillospirales).
