Figure 1.

Heat map differentiation of metabolite. Average metabolite variability of blood plasma between PD patients (n = 43) and healthy controls (n = 37) are shown. Cluster analyses of the 22 differentially altered metabolites are selected based on significance P value (P < 0.05). The heat map depicts high (red) and low (green) relative levels of metabolite variation.
