Comparison between patients with isolated abdominal stab wounds and patients with both abdominal and extra-abdominal stab wounds in SI-ASW and non-SI-ASW patients

	Abdominal SW only (n = 1274)	Abdominal and extra-abdominal SW (n = 450)	p value
(A) SI-ASW patients
ISS*	1 (1, 4)	5 (2, 11)	<0.0001
Mortality, n^b (%)	7/1135 (0.6)	10/410 (2.4)	0.0024
Abdominal surgery, n^b (%)	676/1272 (53.1)	248/450 (55.1)	0.4722
Non-TL, n^b (%)	298/1272 (23.4)	90/450 (20.0)	0.1347

	Abdominal SW only (n = 4379)	Abdominal and extra-abdominal SW (n = 3441)	p value

(B) Non-SI-ASW patients
ISS^a	4 (1, 9)	9 (2, 14)	<0.0001
Mortality, n (%)^b	22/3614 (0.6)	51/3034 (1.7)	<0.0001
