We evaluated the associations of arteriovenous fistula (AVF), arteriovenous graft (AVG), and tunneled central venous catheter (CVC) use with dialysis adequacy and access-related outcomes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This retrospective study included 285 adults whose index access was first successfully used between 2020 and 2023, with follow-up through 2024. Monthly single-pool Kt\/V (spKt\/V) measurements during the first 6 months were analyzed using mixed-effects models. Recurrent complications were reported as rates per 100 access-years. Cox regression and Kaplan\u2013Meier methods were used to evaluate the first composite complication and permanent access failure, respectively. Models were adjusted for prespecified baseline factors, including a history of urgent-start dialysis, previous access attempts, vascular mapping, and residual kidney urea clearance; the interval from access creation or placement to first successful use was examined in sensitivity analyses.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The AVF, AVG, and CVC groups included 156, 67, and 62 patients, respectively, and contributed 1,632 adequacy measurements. Compared with CVC use, adjusted monthly spKt\/V was higher with AVF use (\n                      <jats:italic>\u03b2<\/jats:italic>\n                      \u2009=\u20090.23, 95% confidence interval [CI] 0.17\u20130.29;\n                      <jats:italic>P<\/jats:italic>\n                      \u2009&amp;lt;\u20090.001) and AVG use (\n                      <jats:italic>\u03b2<\/jats:italic>\n                      \u2009=\u20090.11, 95% CI: 0.04\u20130.18;\n                      <jats:italic>P<\/jats:italic>\n                      \u2009=\u20090.002). Recurrent composite-complication rates were 8.84, 26.60, and 54.69 per 100 access-years, respectively (\n                      <jats:italic>P<\/jats:italic>\n                      \u2009&amp;lt;\u20090.001).
