Discriminatory performance of BMI, albumin, indication of surgery, pancreas thickness, pancreas texture, and the formulated nomogram for detecting patients with CR-POPF after PD

Variables	AUC (95% CI)	Cut off	Sensitivity	Specificity	PPV	NPV
BMI	0.654 (0.560–0.747)	–	0.658	0.649	0.481	0.794
Albumin	0.652 (0.565–0.739)	–	0.421	0.883	0.640	0.756
Pancreas thickness	0.722 (0.620–0.824)	19.3	0.579	0.779	0.564	0.789
Pancreas texture	0.673 (0.580–0.766)	–	0.632	0.714	0.522	0.797
Nomogram	0.842 (0.762–0.921)	102	0.710	0.870	0.730	0.859

BMI body mass index; AUC area under the receiver-operating-characteristic curve; CI confidence interval; PPV positive predictive value; NPV negative predictive value
