Pairing LL-37 levels with CRP levels can indicate UC mucosal disease activity with greater accuracy than using either alone. a Scatter plot shows the negative correlation of Mayo endoscopic scores and serum LL-37 levels of UC patients. b Scatter plot shows the positive correlation of Mayo endoscopic scores and serum CRP levels of UC patients. c ROC curves with AUC values demonstrate the accuracy of using LL-37 alone, CRP alone, and both for indicating UC endoscopic remission. d ROC curves with AUC values demonstrate the accuracy of using LL-37 alone, CRP alone, and both for indicating severe UC endoscopic disease activity
