Study design and outcome reporting were variable between studies. Mean age of patients was comparable (67.7 years versus 65.0 years versus 66.6 years). Mean follow-up duration was comparable between open and laparoscopic groups (46.2 months versus 45.5 months) but reduced in the endoscopic group (33.4 months). The open group had a higher proportion of high grade\/G3 tumors and pT2-4 tumors when compared to the laparoscopic and endoscopic groups (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      \u2009&lt;\u2009.001 and\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      \u2009=\u2009.002).
