Table 4 Grading of Recommendations Assessment, Development and Evaluation certainty of evidence

Outcome	Studies/participants	Design	Risk of bias	Inconsistency	Indirectness	Imprecision	Publication bias	Certainty
Intestinal obstruction	9/2328	Observational cohorts	Residual confounding	Not serious	Not serious	Not serious	Undetected; limited power	Low
Internal hernia	5/618	Observational cohorts	Residual confounding	Not serious	Not serious	Serious (sparse events)	Undetected; limited power	Very low
Anastomotic leak	7/2594	Observational cohorts	Residual confounding	Not serious	Serious (procedure-specific)	Serious	Undetected; limited power	Very low
Unplanned reoperation	6/2360	Observational cohorts	Residual confounding	Not serious	Not serious	Not serious	Undetected; limited power	Low
Hospital stay	3/928	Observational cohorts	Residual confounding	Serious (I² = 87%)	Serious (care pathways)	Serious/unstable	Undetected; limited power	Very low

Observational evidence begins with low certainty. No reliable formal test for publication bias was possible because each outcome included fewer than ten studies.
