PTTA: P-value obtained through t-test. PWKW: P-value obtained through Wilcoxon/Kruskal-Wallis test. PAD: P-value obtained through Anderson-Darling test. *AUCs were obtained from a ROC curve constructed using Eng, J. ROC analysis: web-based calculator for ROC curves. from http://www.jrocfit.org. # the analysis include only these peaks, due to the other peaks of the table were not significant when the manual corroboration in Flex Analysis software was made.
