  1. FC: fold change relative to control
  2. P-value was calculated from student’s t-test
  3. Tier 1 - Positive identification (chemical isotope labelling library);
  4. Tier 2 - High confidence putative identification (linked identity library library)
  5. Only metabolites with both fold-change ≥1.5 or ≤ 0.67 and FDR ≤ 0.01 are shown
