Overexpression of G protein-coupled receptor 31 as a poor prognosticator in human colorectal cancer

Figure 2 Receiver operating characteristic curve analysis used to determine the cutoff value for G protein-coupled receptor 31 expression levels in colorectal carcinoma. The following sensitivity and specificity parameters for each outcome were plotted. A: Differentiation (AUC = 0.463); B: pT status (AUC = 0.452); C: pN status (AUC = 0.489); D: pM status (AUC = 0.623); E: Overall survival (AUC = 0.648); F: Disease-free survival (AUC = 0.634). AUC: Area under curve.
