Prognosis of ulcerative colitis differs between patients with complete and partial mucosal healing, which can be predicted from the platelet count

Figure 1 Kaplan-Meier curves of maintenance of clinical remission for patients with Mayo endoscopic subscore 0, 1 or 2. The cumulative remission maintenance rate showed statistically significant differences among patients with each Mayo endoscopic subscore (MES).

Figure 2 Receiver operating characteristic curve of change in platelet count for identifying the shift from Mayo endoscopic subscore 0 to 1 in patients with clinical remission. The receiver operating characteristic (ROC) curve of change in platelet count for identifying the shift from Mayo endoscopic subscore (MES) 0 to MES 1 had an area under curve of 0.86. When cut-off value of change in platelet count was determined as 1.3 × 10⁴/μL, the sensitivity and specificity were 0.81 and 0.73, respectively.
