Signature 1
Source: Figure 5
Description: Figure 5. Comparative analysis of the microbial communities of groups with and without diabetes at the phylum (A) and genus (B) levels using the linear discriminant analysis (LDA) effect size (LEfSe) method. LDA scores (log 10) for the most prevalent taxa in diabetic patients are represented on the positive scale, whereas LDA-negative scores indicate enriched taxa in the healthy controls.
Abundance in Group 1: increased abundance in diabetic
