Table 3 Comparison of closure performance metrics between the two groups, n (%)

Procedural characteristics	Control group (n = 129)	Experimental group (n = 85)	χ²/t/Z	P value

Number of clips, mean ± SD	7.2 ± 3.3	6.4 ± 2.9	t = 1.788	0.075
Procedure-ending leak test			χ² = 2.005	0.157
Positive	3 (2.3)	0 (0.0)
Negative	126 (97.7)	85 (100.0)
Rescue closure			χ² = 1.330	0.249
Yes	2 (1.6)	0 (0.0)
