Comparison of ROC curves for mucosal inflammation (MES 1 or 2 or 3) of SAA and CRP. The ROC curves of SAA and CRP in patients in clinical remission. In the ROC analysis, the area under the ROC curve of the SAA was 0.749, indicating a higher predictive power, whereas that of the CRP was 0.646. Comparison of ROC curves for mucosal inflammation (MES 1 or 2 or 3) of SAA and CRP showed that SAA was superior and indicated statistical significance (p < 0.01). AUC, area under the receiver’s operating characteristic curve; CI, confidence interval; CRP, C-reactive protein; MES, Mayo Endoscopic Score; SAA, serum amyloid A
