Table 3. Significant urinary metabolites identified by Kruskal-Wallis test according to group (AP: acute pancreatitis, CP: chronic pancreatitis, HC: healthy control). Wilcoxon rank-sum tests with Bonferroni correction are then applied to test these metabolites; those with significant P values (P< 0.05) are bolded. After the significant Wilcoxon rank-sum test results are validated by random permutation, only citrate and adenosine results are significant (P=0.019 and P=0.026, respectively).
