Separation between proteins expressed in samples from patients with right-sided stage II and III CRC. a shows the PCA biplot when all proteins were considered b shows the PCA biplot when only proteins that passed the cutoff of a Mann-Whitney U test p-value of less than 0.05 were considered. Blue dots represent samples from patients with stage II cancer in the right colon and purple dots represent samples from patients with stage III cancer in the right colon. c shows the S-plot generated by OPLS-DA modeling. The upper right quadrant of the S-plot, with positive values, shows proteins with higher levels in samples from patients with right-sided stage III CRC. The lower left quadrant, with negative values, shows proteins with higher levels in samples from patients with right-sided stage II CRC
