Table 5 Logistic regression analysis was performed to evaluate predictive factors for high IBL

From: Effect of obesity on intraoperative bleeding volume in open gastrectomy with D2 lymph-node dissection for gastric cancer

Variable Coefficient Odds ratio (95% CI) p value
Age 0.055 1.057 (1.005–1.112) 0.033
Operative procedure    
   TG/DG 1.555 4.735 (1.832–12.238) 0.001
BMI (kg/m2)    
   ≥25/<25 1.472 4.356 (1.399–13.563) 0.011
  1. IBL = intraoperative blood loss; BMI = body-mass index; CI = confidence limits
  2. P < .05 was considered statistically significant
