Fig. 6. Metabolic correlation networks for liver, kidney and spleen tissues. Metabolites with coefficients of Pearson correlations above a threshold were connected by solid lines color coded according to the values of the coefficients (warm color represented a positive correlation and cool color a negative one), with the line width scaled based on their absolute values. Names of the metabolites in red and blue colors denoted their significant increases and decreases in HDC group mice versus the control mice, respectively. Dotted lines between metabolites represented their structural similarities.
