Does the use of computed tomography scenogram alone enable diagnosis in cases of bowel obstruction?

Table 7 Inter-rater (intra-observation) agreement of the evaluators' diagnoses of obstruction and segmentation on the scenogram, n (%)

	Observer	Positive predict rate	Negative predict rate	κ (95%CI)	P value
Obstruction	I vs II	34 (94.4)	5 (50)	0.498 (0.336-0.660)	0.001
	I vs III	33 (91.7)	6 (60)	0.536 (0.382-0.690)	< 0.001
	II vs III	35 (95.5)	5 (55.6)	0.548 (0.386-0.710)	< 0.001
Segmentation	I vs II	14 (45.2)	11 (73.3)	0.151 (0.03-0.272)	0.228
	I vs III	18 (58.1)	14 (93.3)	0.426 (0.314-0.538)	0.001
	II vs III	13 (68.4)	22 (81.5)	0.503 (0.373-0.633)	0.001
