Table 3 Multivariate logistic regression analysis of anastomotic stricture

Variable	β	SE	Wald χ²	Odds ratio	95%CI	P value
Body mass index ≥ 25 kg/m²	1.186	0.512	5.367	3.274	1.201-8.928	0.021
Diabetes mellitus	1.082	0.498	4.721	2.951	1.112-7.832	0.03
Total gastrectomy	1.324	0.487	7.392	3.758	1.447-9.762	0.007
Stapler diameter 25 mm	1.156	0.476	5.901	3.177	1.250-8.074	0.015
nPV-HU (per 10% increase)	-0.892	0.318	7.869	0.41	0.220-0.765	0.005
PV-HU/aorta-HU (per 0.1 increase)	-0.756	0.287	6.938	0.469	0.268-0.824	0.008

Odds ratio < 1 for normalized portal vein computed tomography (CT) value and portal vein CT value/abdominal aorta CT value indicates that increased values are protective factors, meaning decreased values increase anastomotic stricture risk. aorta-HU: Abdominal aorta computed tomography value; nPV-HU: Normalized portal vein computed tomography value; PV-HU: Portal vein computed tomography value.
