Figure 7. Meta-analysis of incisional hernia
vs. right colectomy. Univariable meta-regression did not identify any of these covariates to be a significant
influence for the primary outcome.
Publication bias: No evidence of publication bias was found for the primary outcome (Begg’s P = 0.520;
Egger’s P = 0.640). Visual examination of funnel plots for those outcomes did not demonstrate asymmetry,
as evidenced in Figure 10.
Leave-one-out analysis for the primary outcome, anastomotic leakage [Figure 11], was conducted to
evaluate the odds ratio when individual studies were removed. No major changes to the results were
observed for anastomotic leakage (OR = 0.84; 95%CI: 0.54-1.32).
