Age- and Diet-Dependent Changes in Hepatic Lipidomic Profiles of Phospholipids in Male Mice: Age Acceleration in Cyp2b-Null Mice

Figure 4

Relationship between treatment groups and measured variables. (a) Principal component analysis (PCA) biplot showing relationships between treatment groups and measured variables such as physiological parameters, serum lipids, and phospholipid species. Variables include serum lipids, WAT somatic index (WSI), body weight, and lipid species in order to associate specific biochemical parameters with different treatment groups (diet and age) and genotypes (WT and Cyp2b-null). (b) Top 10 contributing variables in the PCA plot based on loading strength expressed in percent contribution.
