Receiver operating characteristic (ROC) curve comparing RDW in blue, Hemoglobin in green, Albumin in orange, HRR in purple, and CAPCSI in red, plotting Sensitivity versus 1 minus Specificity, to assess diagnostic performance. — Receiver operating characteristic (ROC) curves comparing the prognostic performance of Canine Acute Pancreatitis Clinical Severity Index (CAPCSI), red blood cell distribution width (RDW), hemoglobin concentration, albumin concentration and hemoglobin-to-RDW ratio (HRR) for predicting in-hospital mortality in dogs with acute pancreatitis. Non-survival was associated with values above the cut-off for RDW and below the cut-off for hemoglobin, albumin, and HRR.
