We aimed to compare outcomes of starting dialysis on arteriovenous fistulas (AVFs) versus arteriovenous grafts (AVGs) in haemodialysis patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We conducted a systematic search of multiple electronic information sources and bibliographic reference lists. The following outcome parameters were evaluated at 1, 2 and 5\u00a0years: primary failure, defined as access never used for dialysis; primary patency, defined as intervention-free access survival; primary-assisted patency, defined as uninterrupted access survival with interventions; and secondary patency, defined as cumulative access survival.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>We identified 15 comparative studies reporting a total of 118,434 patients who initiated haemodialysis with AVF ( n = 95,143) or AVG ( n = 23,291). Our analysis demonstrated that AVF was associated with significantly higher primary failure rate (OR: 2.05, p = .0005) but significantly higher rate of primary patency at 1\u00a0year (OR: 1.91, p &lt; .00001), at 2\u00a0years (OR: 2.52, p &lt; .00001) and at 5\u00a0years (OR: 2.59, p &lt; .00001); and primary-assisted patency at 1\u00a0year (OR: 1.71, p &lt; .00001), at 2\u00a0years (OR: 2.13, p &lt; .00001) and 5\u00a0years (OR: 2.79, p &lt; .00001). There was no significant difference in secondary patency at 1\u00a0year (OR: 1.08, p &lt; .00001) but AVF had better secondary patency at 2\u00a0years (OR: 1.26, p &lt; .00001) and 5\u00a0years (OR: 1.60, p &lt; .00001) than AVG.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The meta-analysis of best available comparative evidence (Level 2) demonstrated that AVFs may be associated with significantly higher primary failure rate but higher primary patency, primary-assisted patency and secondary patency at 1, 2 and 5\u00a0years compared to AVGs.
