Table 4 Diagnostic accuracy of endoscopy using a confidence level score for the prediction of a complete response

	Stringent strategy¹ (only eCR)		Lenient strategy² (eCR + near-eCR)
	R1	R2	R1	R2
Sensitivity, % (n/N)	31.4 (11/35)	28.6 (10/35)	71.4 (25/35)	62.9 (22/35)
95%CI	16.1-46.8	13.6-43.5	56.5-86.4	46.9-78.9
Specificity, % (n/N)	97.3 (107/110)	97.3 (107/110)	81.8 (90/110)	81.8 (90/110)
95%CI	94.2-100.0	94.2-100.0	74.6-89.0	74.6-89.0
Accuracy, % (n/N)	81.4 (118/145)	80.7 (117/145)	79.3 (115/145)	77.2 (112/145)
95%CI	75.1-87.7	74.3-87.1	72.7-85.9	70.4-84.1
PPV, % (n/N)	78.6 (11/14)	76.9 (10/13)	55.6 (25/45)	52.4 (22/42)
95%CI	57.1-100.0	54.0-99.8	41.0-70.1	37.3-67.5
NPV, % (n/N)	81.7 (107/131)	81.1 (107/132)	90.0 (90/100)	87.4 (90/103)
95%CI	75.1-88.3	74.4-87.7	84.1-95.9	81.0-93.8

¹The stringent strategy: Only “endoscopic complete response” was considered as a positive test result.

²The lenient strategy: Both “endoscopic complete response” and “near-endoscopic complete response” were considered as positive test results.

eCR: Endoscopic complete response; near-eCR: Near-endoscopic complete response; PPV: Positive predictive value; NPV: Negative predictive value; CI: Confidence interval.
