Table 6. The risk assessment for delayed post-polypectomy bleeding in the groups according to the withdrawal period of anticoagulants.

Combination of the groups assessed the risk of DPPB^a	Univariate analysis
Combination of the groups assessed the risk of DPPB^a	OR (95% CI)	P value^b
Group B vs. Group A	4.258 (0.423–42.870)	0.219
Group C vs. Group B	0.344 (0.066–1.796)	0.206
Group A vs. Group C	0.682 (0.069–6.744)	0.743

^a, Group A, anticoagulant withdrawal period of ≥2 days; Group B, anticoagulant withdrawal period of 1 day (on the day of colonoscopy); Group C, without anticoagulant withdrawal period (continued). ^b, logistic regression analysis model was used. DPPB, delayed post-polypectomy bleeding; OR, odds ratio; CI, confidence interval.
