1PWKW, p value for Wilcoxon Kruskal Wallis; significant if < 0.05; - These PWKW values illustrate that, from a univariate point of view, these peaks can discriminate between patients with epithelial ovarian cancer and those having benign ovarian masses; - The 20 highlighted peaks were over-expressed in group I, while the other 11 peaks were over-expressed in group II.
