Figure 6

Differential relative abundance of specific genera across the three experimental groups. Metastats model was applied on the bacterial genera with a relative abundance of more than 5% in at least one sample. Genera with lower abundances were grouped in “other”. The three experimental groups are indicated as SSc/GI+ (patients with established SSc and gastrointestinal symptoms), SSc/GI- (patients with SSc without gastrointestinal symptoms), and HC (healthy controls). Significant differences are highlighted by different minor letters (P < 0.05).
