However, recent large randomized clinical trials (RCTs) have reported conflicting results. We performed a meta-analysis of all available RCTs comparing graft patency and clinical outcomes between NT-SV and CON-SV harvesting techniques.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A systematic review was conducted through May 9, 2025 to identify RCTs with systematic imaging follow-up comparing the NT-SV and CON-SV. The primary outcome was graft failure. Secondary outcomes included mortality, major adverse cardiac events (MACE; composite of mortality, myocardial infarction, or repeat revascularization), and leg wound complications. Outcomes were pooled using inverse variance random and fixed effects models.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Eight RCTs involving 4286 patients (NT-SV: 2155; CON-SV: 2131) were analysed. NT-SV was associated with a significantly lower incidence of graft failure than CON-SV (incidence rate ratio [IRR], 0.70; 95% confidence interval [CI] 0.60-0.82; P\u2009&amp;lt;\u2009.001) at a weighted mean follow-up of 3.7 years; this result was solid in multiple sensitivity analyses. Mortality (IRR, 1.03; 95% CI, 0.72-1.47, P\u2009=\u2009.87) and MACE (IRR, 0.89; 95% CI, 0.67-1.18; P\u2009=\u2009.42) were similar between groups. NT-SV was associated with a higher incidence of leg wound complications (IRR, 1.73; 95% CI, 1.32-2.27; P\u2009&amp;lt;\u2009.001).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The NT-SV harvesting technique was associated with a significant reduction in graft failure and an increased risk of wound complications compared to the CON-SV.
