  1. a Variable importance in the projection (VIP) was obtained from PLS-DA model with value higher than 1.0;
  2. b The p-value calculated from two-tailed Student's t test;
  3. c FDR adjusted p value from two-tailed Student's t test;
  4. d Fold change was calculated as binary logarithm of average mass response (normalized peak area) ratio between HUPM and LUPM patients, where the positive value means that the average mass response of the metabolite in the HUPM group is larger than that in the LUPM group.
