Gas chromatography/mass spectrometry based metabolomic study in a murine model of irritable bowel syndrome

Figure 4 Separating the group treated with Clostridium butyricum from the irritable bowel syndrome only group by metabolic profiling analysis. A: Score scatter plot of PCA model for IBS group vs IBS + C. butyricum group; B: Score scatter plot of OPLS-DA model for IBS group vs IBS + C. butyricum group; C: Permutation test of OPLS-DA model for IBS group vs IBS + C. butyricum group; D: Pathway analysis for IBS group vs IBS + C. butyricum group. M: Model (IBS) group; Y: IBS + C. butyricum group; PCA: Principal component analysis; OPLS-DA: Orthogonal projections to latent structures-discriminant analysis; IBS: Irritable bowel syndrome; C. butyricum: Clostridium butyricum.
