Characterization of the feature M206T28 from urine samples of infected patients. a M206T28 normalized to the mean of all features. The dotted line depicts the threshold of 9 (ratio) for O. volvulus infections. The red lines show the means of the corresponding data. Significance calculated with Mann-Whitney U test, GraphPad Prism ver 9.1. b MS/MS spectrum of the feature M206T28. A sample with high content of M206T28 was analyzed by LC-MS on the Q-TOF instrument with fragmentation of the precursor m/z 206.0800 at 20Â V. The spectrum exactly matches that of cinnamoylglycine as found in the Metlin database
