Capsule endoscopy with flexible spectral imaging color enhancement reduces the bile pigment effect and improves the detectability of small bowel lesions

Table 2 Evaluation of the number of false-positive findings for each visibility score

	No. of Segments	No. of false positive findings/segment
	No. of Segments	Conventional	Setting 1	Setting 2	Setting 3
Visibility score
excellent	7	0.1 ± 0.4	0.1 ± 0.4	0.3 ± 0.5	0.4 ± 0.5
good	13	0.3 ± 0.1	0.2 ± 0.6	0.2 ± 0.4	0.5 ± 0.7
fair	20	0.6 ± 0.8	0.9 ± 1.0	1.2 ± 1.1	1.7 ± 1.4^*
poor	8	0.9 ± 0.6	1.6 ± 0.9	2.9 ± 1.9^†	2.6 ± 1.8^†

NOTE: Each of the 12 CE videos was divided into four segments of equal length, according to the small bowel transit time, and landmarks were placed to identify the last 10 minutes of every quartile. The CE experts evaluated the visibility of the each segment of 10 minutes' duration using a 4-point qualitative index (excellent, good, fair and poor).
Values are mean ± SD.
