The receiver operating characteristic (ROC) curve for age, tumor size and jaundice in identifying poorly differentiated pancreatic neuroendocrine neoplasms (PNENs). A: ROC curve for age, tumor size and jaundice alone in predicting poor differentiated PNENs. B: ROC curve for age + size (Model 1) and age + tumor size + jaundice in predicting poor differentiated PNENs.
