Endoscopic submucosal dissection for early gastric cancer and precancerous lesions enhances postoperative recovery and mitigates complication risks

Figure 3 Carcinoembryonic antigen, carbohydrate antigen 125, and carbohydrate antigen 19-9 levels pre- and post-surgery in research and control groups. A: Carcinoembryonic antigen levels in research and control groups; B: Carbohydrate antigen (CA)125 levels in research and control groups; C: CA19-9 levels in research and control groups. CEA: Carcinoembryonic antigen; CA: Carbohydrate antigen. ^aP < 0.01, ^bP < 0.001, reflecting significant changes from preoperative levels; ^cP < 0.05, denoting significant differences from the control group.
