Table 2 Cut-off points and diagnostic values of variables for the distinction between non- appendicitis patients and appendicitis patients.

Variables	Cut-off	Diagnostic values					ROC curve			Odds ratio
Variables	Cut-off	Sensitivity	Specificity	PPV	NPV	Accuracy	Area (SE)	95% CI	P	Odds ratio	95% CI	P
Ileocolic artery diameter	2.475	92.6%	95.6%	95.6%	92.6%	94.09%	0.982 (0.005)	0.973–0.991		273.306	127.318–586.691
Ileocolic vein diameter	3.885	86.4%	97.6%	97.4%	87.5%	91.92%	0.972 (0.006)	0.960–0.985		259.105	106.952–627.716
If both are positive		83.3%	99.2%	99.1%	85.2%	91.14%				620	148.448–2589.445
PPV – positive predictive value; NPV – negative predictive value; ROC – receiver operating characteristic; SE – standard error.
