Risk factors		OR (univariable)	OR (multivariate)
Age groups	≤40 years vs ≥65 years	3.16 (95% CI: 1.37 to 8.18, p=0.010)	2.84 (95% CI: 1.20 to 7.46, p=0.023)
	≤40 years vs 41–65 years	1.26 (95% CI: 0.65 to 2.46, p=0.495)	1.15 (95% CI: 0.58 to 2.29, p=0.694)
Female gender		0.71 (95% CI: 0.37 to 1.30, p=0.274)	0.89 (95% CI: 0.45 to 1.69, p=0.719)
Pancreatic cannulation		4.63 (95% CI: 2.51 to 8.59, p<0.001)	3.64 (95% CI: 1.93 to 6.92, p<0.001)
Pancreatic injection		2.00 (95% CI: 0.80 to 4.30, p=0.101)	0.64 (95% CI: 0.41 to 1.85, p=0.219)
Pancreatic stenting		2.97 (95% CI: 1.00 to 7.11, p=0.026)	1.2 (95% CI: 0.54 to 3.18, p=0.935)
Native papilla		0.33 (95% CI: 0.15 to 0.66, p=0.003)	0.46 (95% CI: 0.2 to 0.97, p=0.05)

P value<0.05 is considered significant.
