Fig. 3.

Results of multivariate analysis among three groups. Each dot with three kinds of color (green, H-HF model group; red, CON group; purple, SR group) represented the different sample. a: PCA score plots of among three groups (R²X = 0.632); b: Venn diagram showed the overlapping and unique differential metabolites amongst the comparison groups. c: OPLS-DA score plots of CON and H-HF group (R²X = 0.505, R²Y = 0.997, Q² = 0.977); d:The permutation test(n = 200) for the OPLS-DA model of CON and H-HF group; e: OPLS-DA score plots of H-HF and SR group (R²X = 0.387, R²Y = 0.976, Q² = 0.736); f: The permutation test (n = 200) for the OPLS-DA model of H-HF and SR group
