Table 2 Sensitivity, specificity, and accuracy with which CH-endoscopic ultrasonography, color Doppler endoscopic ultrasonography, and the standard endoscopic ultrasonography variables differentiate malignant from benign lymph nodes

	Sensitivity (95%CI)	Specificity (95%CI)	Accuracy (95%CI)	P value¹
Short axis 13 mm or longer	72% (34/47) (62-81)	85% (74/87) (79-90)	81% (108/134) (73-86)	0.27
Long axis 20 mm or longer	72% (34/47) (61-82)	63% (55/87) (57-68)	66% (89/134) (59-73)	0.001
Round shape	62% (29/47) (51-72)	75% (65/87) (69-80)	70% (94/134) (62-77)	0.008
Sharp edge	81% (38/47) (71-89)	30% (26/87) (24-34)	48% (64/134) (41-53)	< 0.001
Hypoechogenicity	66% (31/47) (55-76)	61% (53/87) (55-66)	63% (84/134) (55-70)	< 0.001
