Table 1 Baseline characteristics of study population (n = 398)

	n (%)
Sex (M/F) (% M)	302/96 (75.6)
Age (yr)	68.0 ± 10.2
Hypertension (-/+) (% positive)	208/190 (47.7)
Diabetes mellitus (-/+) (% positive)	349/49 (12.3)
Drugs potentially related to gastric injury/bleeding (-/+) (% positive)	330/68 (17.1)
Location (UM/L) (% L)	252/146 (36.7)
Depth (m/sm) (% sm)	343/55 (13.8)
Ulcer (-/+) (% positive)	367/31 (7.8)
Diameter of lesion (cm)	43.1 ± 17.2
Duration of operation (min)	69.0 ± 56.7
Coagulator (expert/beginner) (% beginner)	182/216 (54.3)

Quantitative data are presented as mean ± SD.

Table 2 Background characteristics in relation to bleeding status (mean ± SD) n (%)

	Bleeding (-) (n = 375)	Bleeding (+) (n = 23)
Sex (M/F) (% M)	283/92 (75.4)	19/4 (82.6)
Age (yr)	67.8 ± 10.2	70.1 ± 10.0
Hypertension (-/+) (% positive)	198/177 (47.2)	10/13 (56.5)
Diabetes Mellitus (-/+) (% positive)	329/46 (12.2)	20/3 (13.0)
Drugs potentially related to gastric injury/bleeding (-/+) (% positive)	315/60 (16.0)	15/8 (34.8)^a
Location (UM/L) (% L)	243/132 (33.2)	9/14 (60.9)^a
Depth (m/sm) (% sm)	324/51 (13.6)	19/4 (17.4)
Ulcer (-/+) (% positive)	347/28 (7.4)	20/3 (13.0)
Diameter of lesion (cm)	42.7 ± 17.2	48.3 ± 17.3
Duration of operation (min)	68.8 ± 56.7	72.2 ± 56.4
Coagulator (beginner/expert) (% beginner)	197/178 (52.5)	19/4 (82.6)^a

^aP < 0.05 vs bleeding (-). P values by χ² test and Student’s t-test.

Table 3 Significant predictors of post-ESD bleeding identified by multiple logistic regression

Characteristics	Odds ratio	95% CI	P
Drugs potentially related to gastric injury/bleeding	2.76	1.09-6.98^a	0.032
Tumor in lower third of stomach	2.47	1.02-5.96^a	0.044
Beginner coagulator	3.93	1.29-11.91^a	0.016

^aP < 0.05. ESD: Endoscopic submucosal dissection.

Table 4 Risk factors for post-ESD bleeding according to bleeding site

	Marginal bleeding (n = 17)	Central bleeding (n = 6)
Drugs potentially related to gastric injury/bleeding	6 (35.3)	3 (50.0)
Tumor in the lower third of stomach	9 (52.9)	5 (83.3)
Beginner coagulator	16 (94.1)	3 (50.0)^a

^aP < 0.05 vs marginal bleeding. P values by χ² test.
