Table 3 Method-dependent accuracy rates and tests of significance (proximal vs distal stenosis) with respect to the localization of bile duct stenosis n (%)

Method	Stenosis (localization)	Accuracy	95%CI	P value
Method	Stenosis (localization)	Accuracy	95%CI	(prox. vs distal)
IDUS	Proximal	28 (100)	100-100	0.419
	Distal	165 (89)	85-94
ETP	Proximal	13 (46)	28-65	0.275
	Distal	93 (62)	55-70
IDUS + ETP	Proximal	28 (100)	100-100	0.505
	Distal	167 (90)	86-95
EUS	Proximal	16 (57)	39-75	< 0.0001
	Distal	147 (79)	74-85
CT	Proximal	25 (89)	79-100	0.09
	Distal	132 (71)	65-78
