Figure 9
Histogram of the number of peptide masses with Wilcoxon-Mann-Whitney probability p-values of the control versus the breast cancer with LM group. All 1949 identified peptide masses in the matrix are presented as a function of the Wilcoxon-Mann-Whitney probability p-value. The white bars represent the frequency of the peptide masses with a p-value in the control group, while the black bars represent the frequency of the peptide masses with a p-value in the breast cancer with LM group. 152 peptide masses are significantly differentially expressed in the breast cancer with LM group (p-value less than 0.01, ranging from 1.1 * 10-6 to 9.8 * 10-3).
