Comparison of preoperative and postoperative indicators. (A) The Karnofsky score was improved post-treatment, compared with pre-treatment (t = 11.22, P < 0.0001). (B) the ΔKPS was higher in 8 patients with esophageal stent implantation (21.3 ± 3.5), which was compared with the ΔKPS in 27 patients with nutritional tube implantation (9.3 ± 3.9, t = 7.87, P < 0.0001). ΔKPS = post-treatment Karnofsky score—preoperative Karnofsky score; *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001.
