Fig. 5

Unsupervised separation of plasma and SBF samples. Samples were separated based on molar percent of lipids using a principal component analysis (PCA). PCA score plot (a) and corresponding loading scatter plot (b) (n = 18 × 2). Samples from the same subject are connected with a line in the PCA plot. The model included 191 lipid variables. The ellipse in A shows Hotelling’s T2 (95% confidence limit). Lipid species are colored according to lipid class as shown in the legend. CE, cholesteryl ester; DG, diglyceride; LPC, lysophosphatidylcholine; LPE, lysophosphatidylethanolamine; PC, phosphatidylcholine; PE, phosphatidylethanolamine; PI, phosphatidylinositol; SM, sphingomyelin; TG, triglyceride
