Identification of Novel Biomarkers for Evaluating Disease Severity in House-Dust-Mite-Induced Allergic Rhinitis by Serum Metabolomics

Figure 1

Metabolomics analysis of serum samples from the MAR group and control group. Score plot with OPLS-DA in the ESI+ (a) and ESI- (c) modes in MAR patients and controls. Permutation test of the OPLS-DA model in the ESI+ (b) and ESI- (d) modes. The values of and represent the goodness of fit and predictability of the model, respectively. OPLS-DA: orthogonal partial least square discriminant analysis; ESI: electrospray ionization; MAR: mild allergic rhinitis.
