Early Kidney Transplantation or Conversion to Peritoneal Dialysis after First-Time Arteriovenous Access Creation.
Article in Annals of vascular surgery, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundAfter autogenous arteriovenous (AV) access creation for end-stage renal disease, a majority of patients will continue on hemodialysis (HD), a minority will receive definitive treatment with kidney transplantation, and a subset of patients will convert to peritoneal dialysis (PD). Our goal was to identify patient factors associated with early transition from HD to either kidney transplantation or PD.
methodsThis is a case-control study of all patients with first-time AV access creation in the Vascular Quality Initiative (2011-2022) who had long-term follow-up. Patients who remained on HD after AV access creation were the control group while patients who received early kidney transplant or who converted to PD were the 2 case groups. Relationship among demographics, comorbidities, neighborhood social disadvantage, and functional status as they relate to renal replacement therapy modality was assessed.
resultsThere were 19,782 patients included; the average age was 62 ± 15 years and 57% were male. During the follow-up period of a median 306 (71-403) days, 1.3% underwent a kidney transplantation and 2.3% underwent conversion to PD. On univariable analysis, rates of kidney transplantation or conversion to PD varied with race (P < 0.001), insurance status (P < 0.001), area deprivation index (ADI) quintile (P < 0.001), and several medical comorbidities. On multivariable analysis, impaired ambulation, current smoking, Medicaid or Medicare insurance, Black race, heart failure, body mass index, and older age were associated with decreased transplantation rates. Conversion to PD was associated with ADI Q5, Q4, and Q3. Decreased conversion to PD was associated with impaired ambulation, Hispanic ethnicity, Black race, former smoking, medication-controlled diabetes, and older age.
conclusionsDecreased kidney transplantation was associated with Black race and noncommercial health insurance but not ADI quintile, suggesting disparities exist beyond community-level access to care. Early kidney transplantation conveyed a 3-year survival benefit compared with HD and PD, which had similar survival. Furthermore work is required to increase access to kidney transplantation and PD.
