From: Molecular response to induction chemotherapy and its correlation with treatment outcome in head and neck cancer patients by means of NMR-based metabolomics

Fig. 1

a The R2X scaled (the distances in the plot correspond to the explained variation) score plot obtained from the OPLS-DA analysis of the 1H CPMG NMR spectra of the serum samples from the LA-HNSCC patients before (preCHT, ) and after (postCHT, ) induction chemotherapy. b The R2X scaled predicted (tPS) score plot from the OPLS-DA analysis. The predicted samples from the external test set are correctly classified. c The OPLS-DA s-line plot indicating the metabolites that differentiate the preCHT and postCHT groups. The correlation of the particular metabolites towards a segregation between the groups (p(corr)) is assessed according to the associated color bar
