Comparison of sensitivity, specificity and predictive values between the groups that did and did not receive endoscopic ultrasound (EUS)

	Diagnosis	Sensitivity	Specificity	PPV	NPV
No-EUS	LGD	91	77	72	93
	HGD	50	93	20	98
	ADC	72	96	96	86
EUS	LGD	100	93	93	100
	HGD	50	96	50	96
	ADC	85	100	100	88

PPV, positive predictive value; NPV, negative predictive value; LGD, low-grade dysplasia; HGD, high-grade dysplasia; ADC, adenocarcinoma.
