RBCs of the patients with acute VTE exhibit a distinct metabolomic signature. a PLS-DA analyses show that the metabolome is able to discriminate between acute VTE patients and control patients, with those metabolites contributing to separation shown in the volcano plot (b) and VIP score graph (c). d Heatmap hierarchical clustering analyses using the 25 metabolites with the lowest p value (Wilcoxon test) indicate that there is good clustering between groups
