¹31 IPMN cases (17 benign; 14 malignant) had data types (clinical data, miRNA, radiomic, lncRNA) included in these analyses. AUC = area underneath the curve; SE = sensitivity; SP = specificity; PPV = positive predictive value; NPV = negative predictive value; High risk stigmata = main pancreatic duct involvement/dilatation ≥10 mm, obstructive jaundice with a cystic lesion in the pancreatic head, or an enhanced solid component/nodule within the cyst; Worrisome features = main pancreatic duct dilation 5–9 mm, cyst size >3 cm, thickened enhanced cyst walls, non-enhanced mural nodules, or acute pancreatitis.
