Venn diagram and heatmap plot from the comparisons of DVT, sham, and control groups. (A) Venn diagram of different spectral regions. The numbers in the overlapping areas (encircled in red) represent different spectral regions between the DVT group and the other two groups, but not between the control and sham groups. (B) Heatmap plot of the different metabolites. Red color indicates a higher level and green color indicates a lower level.
