Notes:
DAve, difference between the maximal and the minimal average peak intensity of all classes; PW/KW, P-value obtained through Wilcoxon/Kruskal–Wallis test; PAD, P-value obtained through Anderson–Darling test; MALDI-TOF MS, matrix-assisted laser desorption ionization time-of-flight mass spectrometry.
