Figure 3 Forest plot. A: Of risk of incomplete total mesorectal excision following laparoscopic total mesorectal excision (LTME) vs open total mesorectal excision (OTME) for rectal cancer. Odds ratios are shown with 95%CIs; B: Of risk of risk of circumferential resection margin positivity following LTME vs OTME for rectal cancer. Odds ratios are shown with 95%CIs; C: Of number of harvested lymph nodes following LTME vs OTME for rectal cancer. Standardized mean differences are shown with 95%CIs; D: Of recurrence following LTME vs OTME for rectal cancer. Odds ratios are shown with 95%CIs; E: Of length of stay following LTME vs OTME for rectal cancer. Standardized mean differences are shown with 95%CIs; F: Of complications following LTME vs OTME for rectal cancer. Odds ratios are shown with 95%CIs; G: Of all-cause mortality following LTME vs OTME for rectal cancer. Odds ratios are shown with 95%CIs; H: Of anastomosis leak following LTME vs OTME for rectal cancer. Odds ratios are shown with 95%CIs; I: Of surgical site infection following LTME vs OTME for rectal cancer. Odds ratios are shown with 95%CIs.
