Figure 1
Figure 1 Comparison of cumulative survival rates between laparoscopic total gastrectomy and open total gastrectomy. A: Before propensity score matching (PSM); B: After PSM. There was no statistically significant difference in overall survival between the two groups before (P = 0.111) and after PSM (P = 0.205). LTG: Laparoscopic total gastrectomy; OTG: Open total gastrectomy; OS: Overall survival; PSM: Propensity score matching.

Figure 2 Forest graph of multivariate COX analysis of prognostic factors for overall survival. Pathological T stage and N stage were found as independent risk factors for overall survival. OS: Overall survival; HR: Hazard ratio; CI: Confidence interval; TRG: Tumor regression grading; NAC: Neoadjuvant chemotherapy.
