Signature 1
Source: Figure 3, Table 2
Description: Microbial signatures of the gut microbiota of MS patients. (A) Barplots comparing the abundances of differentially abundant taxa between MS and control. These “signature” taxa are selected by Wilcoxon rank-sum tests and a false discovery rate of 5%. Error bars represent standard errors. Phylum, family and genus-level taxa are plotted.
Differentially abundant taxa between MS and control samples at phylum, family and genus-level.
