Differences in fecal microbiota composition in CD patients and healthy subjects (HS). Fecal samples from CD patients 1 year after ileocaecal resection (n = 21) and from HS (n = 7) were analyzed by the GA-map™ Dysbiosis test. a PCA plot of CD patients and HS based on fecal bacterial taxa (X-variables; n = 54). Lines to the centroid, showing the group mean, connect each group. OPLS-DA scatter plot (b) and loadings column plot (c) of CD patients and HS (Y-variables) and fecal bacterial taxa (X-variables; VIP > 1.1; n = 21). Statistically significant differences between study groups are indicated with asterisks in the OPLS-DA loadings column plot (* p ≤ 0.05; ** p ≤ 0.01; *** p ≤ 0.001; **** p ≤ 0.0001)
