Table 5

Comparison of cannulation outcomes in the OT-WGC and OT-CGC groups by coarsened exact matching.

	OT-WGC ()	OT-CGC ()	OR or coefficient (95% CI)		Statistical method
Number of unintended pancreatic access events			0.514 (0.274-0.165)	0.038	Ordinal logistic regression
Biliary cannulation time (seconds)			113.8 (-58.657-286.356)	0.194	Linear regression
Frequency of rescue cannulation (%)	22.4% (15/67)	24.1% (18/74)	0.89 (0.406-1.949)	0.77	Logistic regression
Successful biliary cannulation rate (%)	98.5% (66/67)	96.8% (72/74)	2.21 (0.209-23.305)	0.51	Logistic regression
Incidence of PEP (%)	3% (2/67)	8.7% (6/74)	0.31 (0.062-1.597)	0.163	Logistic regression
