Quantitative comparison of normalized abundance of total BSBGs between healthy and IBD individuals in (a). Spanish cohort, and (b). American cohort. The shape refers to the kernel probability density of the data at different values. The boxplots inside the violin plot represent the interquartile range between the first and third quartiles with the median line inside the boxes, whereas the whiskers indicate the minimum and maximum values from the data distribution. The asterisks on the top indicate ns: p > 0.05, *: p < = 0.05, **: p < = 0.01, ***: p < = 0.001, ****: p < = 0.0001 (Mann-Whitney Wilcoxon test). IBD subjects diagnosed with subtype Crohn’s disease and Ulcerative colitis is abbreviated as CD and UC respectively
