GC/MS-Based Metabolomics Reveals Biomarkers in Asthma Murine Model Modulated by Opuntia humifusa

Figure 3

PCA (a) and PLS-DA (b) score plots derived from GC/MS data of serum samples between OVA-induced group and dexamethasone treatment group, suggesting metabolic differences induced by dexamethasone treatment. Panel (c) shows box plots of identified metabolites contributing to differentiation in the PLS-DA model (VIP > 1.2 and p < 0.05). The PLS-DA model was validated by a permutation test (n = 200).
