CP and fatty liver disease: The diagnostic accuracy of ORM1 and ceruloplasmin for mild hepatic steatosis (ROC 0.911, 95% CI 0.763–1.000, p = 0.008 (sensitivity 87.5% and specificity 85.7%) and ROC 0.964, 95% CI 0.877–1.000, p = 0.003 (sensitivity 100.0% and specificity 85.7%)) and severe hepatic steatosis (ROC 0.625, 95% CI 0.366–0.884, p = 0.135 (sensitivity 66.7% and specificity 62.5%) and ROC 0.708, 95% CI 0.474–0.943, p = 0.123 (sensitivity 58.3% and specificity 87.5%)) was calculated based on the expression intensity of proteomic data (Figure 4E).
