Heat map of the differentially abundant metabolites. Each row represents a metabolite, each column a patient color-coded according to its group. The overlying dendrogram is a graphical representation of patient similarity assessed by the euclidean distance: patients in the same cluster are more similar than patients in two separate clusters. The relative intensities were scaled by rows. Some samples were discarded due to quality checks. N = 40 patients analyzed for the metabolomics (Septic shock n = 17, cardiogenic shock n = 6, brain dead n = 17).
