Figure 2: Receiver operator curves and corresponding area under curve analyses demonstrating the accuracy of CTSI, BISAP, WCC, NR, LR, NC, LC, HCT, and NLR as predictors for the severity of acute pancreatitis on admission. CTSI: Computed tomography severity index, BISAP: Bedside Index for Severity in Acute Pancreatitis, HCT: Hematocrit, LC: Lymphocyte count, LR: Lymphocyte ratio, NC: Neutrophil count, NLR: Neutrophil–lymphocyte ratio, WCC: White cell count
