(A) The PLS-DA of 1H NMR urine spectra is measured from 41 children with NE (red colored dots) and 27 healthy controls (green colored dots). The score plot shows the model discrimination between the two groups based on the global metabolites identified in urine. 29.3% and 10.2% are the scores of components 1 and 2, respectively. (B) In the heat map, it illustrates the degree of the 17 differential urinary metabolites discovered contributes the group separation.
