Table 1 Comparison of microbiota composition in biopsies

From: Development of gut inflammation in mice colonized with mucosa-associated bacteria from patients with ulcerative colitis

Sample 1 Sample 2 P P (Bonferroni corrected)
Unweighted UniFrac

  1. Biopsies show significant inter-individual differences only in presence of low abundance taxa as showed by qualitative (unweighted UniFrac) but not abundance-aware (weighted UniFrac) quantitative analysis. Statistically significant results are marked with asterisk
