Fig. 3From: Combined prognostic nutritional index ratio and serum amylase level during the early postoperative period predicts pancreatic fistula following pancreaticoduodenectomyReceiver operating characteristic curves for the combination of PNIP3-P1 ratio and serum amylase level on POD 1 (a), drain amylase level on POD 1 (b), and serum CRP level on POD 3 (c) for prediction of clinically relevant postoperative pancreatic fistula in patients who underwent pancreaticoduodenectomy. PNI, prognostic nutritional index; POD, postoperative day; CRP, C-reactive protein; AUC, area under the curveBack to article page
