Figure S1, which shows the PCA scores and 1D loadings line plots built from the preoperative spectral data only. These plots show a difference in the plasma metabolic profiles between patients with high and low AT even before surgery; Table S1 reports the spectral bins (and hence metabolites) responsible for separating the preoperative and postoperative plasma samples in the PCA scores plots in Figure 1 of the main text; Finally, Figure S2 shows the scores and 1D loadings line plots for the predictive component of an OPLS model created using the postoperative spectral data normalised to the preoperative data regressed against the AT values of the patients, where AT was considered a continuous variable, rather than using the cut off “high” and “low” AT values as in the main text.
