Table 3 Rates of bleeding after vessel-sealing with endoknife compression for all vessels and large vessels

	S method	F1-10 method	P2 value	OR	95%CI
Rate of bleeding	16.3% (8/49)	4.8% (3/62)	0.058	3.84	0.96-15.34
Rate of large vessel bleeding1	26.9% (7/26)	3.4% (1/29)	0.021	10.32	1.17-90.78

¹Large vessels were defined as those with > 2 mm diameter;

²Fisher's exact test was used.
