Figure 3

Correlation heatmaps of differential metabolites. (a) Differential metabolite correlation heatmaps for atrial appendage samples. (b) Differential metabolite correlation heatmaps for plasma samples. The color scale (right) indicates the degree of correlation of the differential metabolites; red represents a positive correlation, while blue represents a negative correlation. In addition, 1 and −1 indicate the strongest positive and negative correlations, respectively.
