The 3-year overall survival rate is significantly better in the NC group than in the C group (p = 0.033). b Disease-free survival curves for 239 patients who underwent curative gastrectomy for gastric cancer. The 3-year disease-free survival rate is significantly better in the group of patients without complications than in the group with complications (p = 0.034)
