Comparison of the β-diversity index between patients with UC and individuals without IBD. (A) Principal coordinate analysis and (B) PCA were performed using the β-diversity metrics based on the weighted UniFrac distance within patients with UC and non-IBD controls. The P-value was calculated using a non-parametric multivariate analysis of variance. There were differences in the composition of the microbial population between patients with UC and non-IBD controls. (C) Analysis of the unweighted pair group method with arithmetic mean clustering between the two groups. UC, ulcerative colitis; IBD, inflammatory bowel disease; PCA, principal component analysis; PC1, principal coordinate 1; PC2, principal coordinate2.
