Table 2 Performance characteristics of EUS imaging, PCF fluid analysis (CEA and cytology), and EUS-FNA results (imaging, CEA and cytology) for malignant cysts identification

From: Endoscopic ultrasound with fine needle aspiration is useful in pancreatic cysts smaller than 3 cm

Malignant cysts (7/19) Sensitivity (95% CI) Specificity (95% CI) PPV (95% CI) NPV (95% CI) Accuracy (95% CI) Area under the ROC (CI)
EUS-imaging 38 (9–76) 55 (23–83) 33 (14–59) 60 (41–76) 48 (25–72) 0.60 (0.30–0.90)
EUS-FNA (CEA + cytology) 86 (42–99) 50 (21–79) 50 (35–66) 86 (47–98) 63 (38–84) 0.80 (0.58–1.00)
