Comparative efficacy and safety between endoscopic submucosal dissection, surgery and definitive chemoradiotherapy in patients with cT1N0M0 esophageal cancer

Figure 2 Cox regression estimates of overall survival and recurrence-free survival after inverse probability of treatment weighting analysis among patients with cT1N0M0 EC who underwent endoscopic submucosal dissection, surgery and definitive chemoradiotherapy. A: Multivariate analysis showed that treatment method, histology and depth of infiltration were independently associated with overall survival; B: Multivariate analysis showed that treatment method, histology and depth of infiltration were independently associated with recurrence-free survival (RFS). CR: Complete response. (^*) represents the significant difference, and the more the number of “^a”, the greater the difference.
