Fig. 4From: Molecular response to induction chemotherapy and its correlation with treatment outcome in head and neck cancer patients by means of NMR-based metabolomicsThe box plot representation of the relative changes in the metabolites identified by OPLS-DA as important to differentiate the preCHT and postCHT samples. The results are presented separately for males (M) and females (F). The decrease of glucose and alanine in M results from the increased pre-treatment levels of these metabolitesBack to article page
