Impact of body mass index on short-term outcomes of laparoscopic gastrectomy in Asian patients: A meta-analysis

Figure 1 Flowchart of study selection in the meta-analysis. LTG: Laparoscopic total gastrectomy.

Figure 2 Correlation between body mass index and short-term outcomes/difficulties in laparoscopic gastrectomy. A: Correlation between body mass index (BMI) and postoperative complications in laparoscopic gastrectomy; B: Correlation between BMI and the duration of the postoperative hospital stay; C: Correlation between BMI and postoperative mortality; D: Correlation between BMI and the time to resuming food intake; E: Correlation between BMI and the operative time; F: Correlation between BMI and blood loss. SMD: Standard mean difference.
