Altered metabolites in plasma among pCR and non-pCR patients. a Pie chart illustrating the abundance ratio of different classes of metabolites detected by untargeted metabolic profiling in plasma samples from ESCC patients. b-f Five identified metabolites that differed significantly between pCR and non-pCR groups using unidimensional analysis. g Hierarchical clustering of significantly different metabolites. The tree structure on the left side represents the clustering relationships of each metabolite, and the tree structure at the top represents the clustering relationships of each sample
