Fig. 2

A Principal component analysis (PCA) plot showing the relationship between samples. The data are displayed across the two main principal components (PC1 and PC2). Each point represents one sample and each colour represents diet period. Closer clustering between points indicate higher relative commonality with respect to bile acid composition in those samples. Concomitantly, larger distances between points indicate lower relative commonality of bile acid composition in those samples. The first axis, PC1 accounted for 55% of the variability and PC2 accounted for 20% of the variability. The directions of the vectors (blue lines) corresponding to BA, particularly LCA, UDCA and DCA are directed towards the HMB samples. CD1 Commercial dry food given the first 2 weeks of the study, yellow points; CD2 commercial dry food given the last 2 weeks of the study, orange points, HMB high minced beef, black points, CA cholic acid, CDCA chenodeoxycholic acid, DCA deoxycholic acid, LCA litocholic, UDCA ursodeoxycholic acid, Taurine-conj. BA (taurine-conjugated CA, CDCA, DCA, and LCA)
