Red cell distribution width: A predictor of the severity of hypertriglyceridemia-induced acute pancreatitis

Table 2 Overall accuracy of red cell distribution width (RDW), bedside index for severity in acute pancreatitis (BISAP), acute physiology and chronic health evaluation II, and BISAP plus RDW score for predicting persistent organ failure in patients with hypertriglyceridemia-induced acute pancreatitis on admission

Variable	AUC	Cut-off	Sensitivity (%)	Specificity (%)	PPV (%)	NPV (%)
RDW	0.85	13.1	82.4	77.9	65.1	89.8
BISAP	0.82	2	64.7	82.4	64.7	82.4
APACHE II	0.74	5	73.5	60.3	48.1	82.0
BR	0.89	2	91.2	67.6	58.5	93.9

HTG-AP: Hypertriglyceridemia-induced acute pancreatitis; AUC: Area under the curve; PPV: Positive predictive value; PPV: Negative predictive value; RDW: Red cell distribution width; BISAP: Bedside index for severity in acute pancreatitis; APACHE II: Acute Physiology and Chronic Health Evaluation II; BR: BISAP plus RDW.
