Fig. 7. SUS-plots and Venn plots for liver, kidneys and spleen tissues. In the SUS-plot between the HDC group and the LDC group, metabolites close to the red diagonal line were equally affected in both groups, while metabolites in the rectangular frame were uniquely affected in one group. The Venn plot helped to visualize metabolites that shared between classes in a positive and negative correlation as well as those belonged uniquely to a specified class.
