It is very uncertain whether summary of findings table ‐ Off‐midline closure changes wound infection compared with tension‐free midline closure (very low certainty).
Summary of findings table ‐ Off‐midline closure (Karydakis flap) showed no clear difference in wound infection compared with off‐midline closure (Limberg flap) (low certainty).
Summary of findings table ‐ Off‐midline closure probably leads to lower wound infection compared with conventional midline closure (moderate certainty).
