Figure 2

Compositional structure of the gut microbiota in SCI. Pie charts showing the average relative abundance of the most abundant phyla (A) and families (B) in SCI patients as compared to age- and sex-matched healthy Italian controls. Only taxa with relative abundance > 0.1% in at least 20 samples for phyla and > 0.01% in at least 30 samples for families are shown. (C) Box plots showing the distribution of the relative abundance values of discriminant genera between SCI patients and healthy controls, according to Random Forests. p < 0.001, Wilcoxon rank sum test.
