Incidence and Risk Factors of Primary Arteriovenous Access Failure in Dialysis Patients: A National-Based Retrospective Cohort Study.
Article in Health science reports, 2025. 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
Background and Aim: The demand for hemodialysis (HD) among patients with end-stage kidney disease (ESKD) is rising globally. A well-functioning vascular access (VA) is crucial for effective dialysis therapy. This study aims to determine the incidence and risk factors of primary arterio-venous access (AVA) maturation failure in HD patients. Methods: This retrospective cohort study included adult HD patients who underwent AVA creation between 01/01/2021 and 31/12/2023 in Qatar. Data, including demographics, medical comorbidities, AVA type, time to maturation, and incidence of AVA failure, were obtained from a national electronic health record system. Results: Among 242 AVA creations, the primary AVA failure rate was 28%, with an incidence of 9.3 per 100 cases per year. Failure was significantly higher in older patients ( Conclusion: Primary AVA failure in hemodialysis patients in Qatar is notably high, with advanced age, diabetes, atherosclerosis, and low blood pressure increasing risk. Statin use and higher systolic blood pressure provide protective effects. These findings highlight the need for managing risk factors to improve AVA maturation success and enhance dialysis outcomes.
