Table 4. Multivariate analysis of post-ESD bleeding with a Cox proportional hazards regression model in the no APT and single APT groups.

	Hazard ratio	95 % Confidence interval	P value
Single APT	2.7	1.1 – 6.6	0.03
Continuous LDA	0.8	0.2 – 3.6	0.72
Diameter of resected specimen ≥ 40 mm	2.7	1.2 – 5.9	0.01

APT, antiplatelet therapy; LDA, low dose aspirin; Note: The Cox proportional hazards regression model was used.Single APT and a diameter of the resected specimen ≥ 40 mm were significant risk factors for post-ESD bleeding, but continuous LDA was not a significant risk factor for post-ESD bleeding.
