Description: Quantitative changes in the bacteria generic composition of the intestinal microbiome in patients with ulcerative colitis relative to control group.
Changes in species composition of intestinal microbiome in patients with ulcerative colitis relative to control group (∗Pvalue≤0.05, ∗∗Pvalue≤0.01, ∗∗∗Pvalue≤0.001).
Abundance in Group 1: increased abundance in Ulcerative colitis

Description: Quantitative changes in the bacteria generic composition of the intestinal microbiome in patients with ulcerative colitis relative to control group.
Changes in species composition of intestinal microbiome in patients with ulcerative colitis relative to control group (∗Pvalue≤0.05, ∗∗Pvalue≤0.01, ∗∗∗Pvalue≤0.001).
