Table 5 Non-inferiority test concerning the image quality compliance rate for clinical diagnostic requirements, n (%)

Study group	n	Image quality compliance rate for clinical diagnostic requirements	Rate difference (95%CI)
DSOC group	58	57 (98.28)	0.0615% (-7.4994% to 7.8518%)
FSOC group	56	55 (98.21)	0.0615% (-7.4994% to 7.8518%)

Rate difference = digital single-operator cholangioscopy group - fiberoptic single-operator cholangioscopy group.

DSOC: Digital single-operator cholangioscopy; FSOC: Fiberoptic single-operator cholangioscopy; CI: Confidence interval.
