Nutritional risk index as a predictor of postoperative wound complications after gastrectomy

Table 5 Multivariate analysis of characteristics of patients with wound complications by logistical regression

	Odds ratio (95% CI)	P value
Age (≥ 56.77 vs < 56.77)	1.299 (0.829-2.035)	0.253
Gender (male vs female)	1.253 (0.795-1.976)	0.330
Disease progression (AGC vs EGC)	1.363 (0.873-2.127)	0.157
Surgical methods:		0.400
B-II vs B-I	0.839 (0.365-1.930)	0.679
TG vs B-I	1.511 (0.920-2.483)	0.103
Comorbid diseases		NS
NRI ( ≥ 97.5 vs < 97.5)	0.653 (0.326-0.974)	0.014

NRI: Nutrition risk index; EGC: Early gastric cancer; AGC: Advanced gastric cancer; B-I: Subtotal gastrectomy with Billroth–Ireconstruction; B-II: Subtotal gastrectomy with Billroth–II reconstruction; TG: Total gastrectomy; NS: Not significant; CI: Confidence interval.
