Proteins showing different abundances in plasma samples of patients with intermediate and high-risk PE compared with individuals presenting with low-risk PE, detected by nontargeted 2D-DIGE.

Pos: Position numbers correspond to the position of the proteins in the gel image (Figure 1).
MW/pI: Theoretical molecular weight (MW) in kDa and theoretical pI.
PMF: peptide mass fingerprinting.
NP: Number of peptide mass values matched from MASCOT PMF.
SC: Amino acid sequence coverage for the identified proteins.
Sco: MASCOT MS protein score, obtained from MALDI-TOF/TOF spectra from the top hit and the second one. Larger differences indicate a better result.
FP: Number of fragmented peptide masses by tandem mass spectrometry.
Expect: Quality of an individual match. It is the number of times in the search we could expect to get a match with this score or higher by chance.
