Figure 4. Hierarchical cluster analysis of serum metabolic profile for distinguishing ESCC from healthy controls (CTRL).

Figure 4

The rows represent the results of the expression of metabolites, and the columns show serum samples. The expression values are represented by the color scale. The intensity increases from blue (relatively decreased) to yellow (relatively increased). In the top bar, the light blue color indicates CTRL, and the pink color indicates ESCC patients.
