Clusterization of serum metabolomic profiles and comparisons between metabolomic classification and outcomes in the training set and the validation set. a Discrimination between patients who survived (blue dots, n = 80) and died (red dots, n = 40) using the Random Forest classifier on nuclear Overhauser effect spectroscopy (NOESY) spectra in the training set. b, c The receiver operator characteristic curves and the area under the curve (AUC) scores are presented for the training set (b) and validation set (c)
