  • aMetabolites ranked according to % change for ovarian cancer patients.

  • bChange calculated as difference in median concentration between cancer and healthy group. Values that are significant after Bonferroni correction are indicated.

  • cP value calculated using Wilcoxon's rank-sum test.

  • dVariable rank was determined from the OPLS-DA variable importance to projection for the two models.
