  1. Uncorrected p-values are based on Mann-Whitney U tests in this study. Correspondence of peptide peaks is based on a difference of less than ± 0.2% of the m/z values of [M+H]+ ions. The column "Change" refers to an increased (U) or decreased (D) abundance of a given peptide in breast cancer samples comparing to control samples, and the column "Identity" shows the protein from which the corresponding fragment is derived. Corresponding peptide peaks were found in six studies based on either MALDI or SELDI spectrometry; patient groups consisted of either early (E), advanced (A) or mixed (M) stages. One study analyzed the nipple aspirate fluid (NAF).
