New-Onset Heart Failure in Hemodialysis Patients: Association With Access Location and Access Flow in a Nationwide Cohort From Sweden.
Article in Kidney medicine, 2026. 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
Rationale & Objective: There is increasing evidence that arteriovenous fistulas (AVFs) might alter cardiac function. Upper arm AVFs are associated with higher access flow, and their use is increasing. It has been hypothesized that the creation of upper arm AVFs would lead to a higher incidence of heart failure compared with forearm AVFs. Study Design: Retrospective cohort study. Setting & Participants: All patients who received a hemodialysis access between 2013 and 2022 in Sweden. Patients with prevalent heart failure or previous hemodialysis were excluded. Exposure or Predictor: Type of hemodialysis access and access flow. Outcome: New-onset heart failure. Analytical Approach: Cox proportional hazards regression for type of access and restricted cubic splines for access flow. Comorbid conditions were included as covariates in both models. Results: In total, 10,170 patients were included. Of those, 6,579 patients with a total of 11,238 accesses remained after excluding patients with prevalent heart failure or prevalent hemodialysis. The risk of new-onset heart failure was comparable between forearm and upper arm AVF ( Limitations: Reliance on International Classification of Diseases (ICD)-10 codes is a limitation because of potential underascertainment and misclassification. The findings may not be generalizable to settings where upper arm AVF are used more liberally than in Sweden. Conclusions: Upper arm AVFs were not associated with the development of heart failure. Comorbid conditions such as ischemic heart disease, heart valve disease, and diabetes as well as age were more important factors for the development of heart failure than access type. The association between access flow and new-onset heart failure is U-shaped.
