Fig. 2

Metabolomic analysis of HA and BL urine samples was conducted, comprising (a) PCA score plot based on the LC–MS Spectra of urine samples from BL and HA, (b) An OPLS-DA model with logarithmic transformation and Pareto scaling for the metabolomics profiling of urine samples, and (c) OPLS-DA Model validation via a permutation test employing n = 20 permutations. (d) Goodness-of-fit parameters generated from the OPLS-DA model, with one predictive (p1) and two orthogonal (o1, and o2) components.
