Additional file 5: of The 1H NMR serum metabolomics response to a two meal challenge: a cross-over dietary intervention study in healthy human volunteers

S-plot in orthogonal projections to latent structures with effect matrix (OPLS-EP) model comparing variables increasing and decreasing in relation to the response vector (Y). The top box is displaying selected metabolites increasing and the bottom box is displaying metabolites decreasing in relation to Y. Grey circles indicate significant (p < 0.05) variables in Wilcoxon signed rank test. (EPS 890 kb
