(A) Principle components analysis (PCA) of individual BA concentrations in PSC patients with No IBD, ulcerative colitis (UC), Crohn’s Disease (CD) or indeterminate IBD (Ind IBD); (B) Plasma BA composition by BA family type in PSC patients by IBD group; (C) Comparison of concentration (μmol/L) and conjugated fraction of total bile acids (TBA) between PSC patients with No IBD and PSC patients with Ind IBD, CD or UC; (D) Comparison of CA:CDCA and CA:DCA ratios between (1) Controls and PSC patients with No IBD and (2) PSC patients with No IBD and PSC patients with Ind IBD, CD or UC. Significance level: *p<0.05, **p≤0.001; Kruskal-Wallis rank sum test. Non-significant comparisons (p≥0.05) are not highlighted in this figure.
