Fig. 3 Volcano maps of the rat plasma metabolites in the sham surgery control and DVT model groups FC: fold change of metabolite in DVT model group versus the control group; P-value: calculated in student t-test which was used to test the significance of metabolites between the two groups. Red dot: the level of metabolite was upregulated in DVT model group. Blue dot: the level of metabolite was downregulated in DVT model group. Gray dot: the level of metabolite was not changed in DVT model group.

Fig. 6 Differential abundance score plot by Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways Different color indicated the different metabolic classifications of the pathway. The positive value of the line segment indicated the pathway was upregulated in DVT model group. The negative value of the line segment indicated that the pathway was downregulated in DVT model group. The size of the segment endpoint indicated the number of differential metabolites involved in the pathway.
