I recently read interestingly “Long-term oncologic outcomes of robotic gastrectomy for gastric cancer compared with laparoscopic gastrectomy” [
1]. The authors compared robotic gastrectomy with laparoscopic gastrectomy for gastric cancer, and it is thought that the results are very meaningful because there are many cases and long follow-up period. Although many cases have been included, they have tried to reduce the bias by performing propensity score matching (PSM) considering that this is a retrospective data collection study. However, while reading the paper interestingly, I found some strange points in the data presented in the paper. …
