Illustration of protein spectra and m/z means of cases and controls.

<p>(A) Representative SELDI-TOF-MS protein spectra of plasma sample from one Control, one RIPC (remote ischemic preconditioning) 5′, and one RIPC 10′ rat. Results are presented as intensities of SELDI-TOF reading (arbitrary units). The 27583, 27791, and 28284 <i>m/z</i> peaks were found to be differentially expressed on the CM10 array as calculated by the Mann-Whitney test. (B) Scattergram showing the significant differences in intensity of 27583, 27791, and 28284 <i>m/z</i> peaks in plasma samples derived from Control, RIPC 5′, and RIPC 10′ rats. The continuous line represents the mean, and dots represent each individual rat (n = 10 in each group). Detailed <i>p-</i>value data for comparison between the three groups is indicated in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0077211#pone-0077211-t001" target="_blank">Table 1</a>.
