Lipid peroxidation phenotype (LPP). (a) Principal component analysis that plots the LPPs Ctrl, Nano-PSO/ROT, ROT/Nano-PSO, and ROT) rats. The graph shows the magnitude of LPP variability and the probability of their variance (ellipses). (b) Complete linkage clustering dendrogram that shows the degree of similitude of the LPPs within and between Ctrl, Nano-PSO/ROT), ROT/Nano-PSO), and ROT rats. The greatest phenotypic similarity is found when the phenotypes are adjacent, are close to the branching points, and appear along with less complex branching patterns.
