Frailty and arteriovenous fistula patency in elderly hemodialysis patients: a retrospective cohort study.
Article in Revista da Escola de Enfermagem da U S P, 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
objectiveTo evaluate the correlation between frailty and AVF patency type in elderly patients in HD.
methodsThis retrospective cohort study evaluated 89 patients from April 2019 to June 2022. The following data were analyzed: 1) Patient characteristics according to the Clinical Frailty Scale (CFS), 2) Charlson score, 3) AVF site (radiocephalic, brachiocephalic, basilic), 4) Patency type (primary and assisted), 5) Mortality. This study was approved by the Ethics Committee of the Oswaldo Cruz University Hospital - University of Pernambuco, under registration no. 4.487.269.
resultsAmong the 89 patients (age = 70 ± 8, 64% female, 36% frail), 42 (47%) had assisted AVF patency, with 26 (62%) being frail. A positive correlation was found between assisted patency and frailty (p = 0.043). During follow-up (548 to 938 days), 33 (37.1%) patients died, with frail patients showing a higher prevalence of CKD and a higher frequency of assisted patency.
conclusionAssisted AVF patency was the most common type among frail elderly patients on hemodialysis. Frailty assessment may be integrated into the clinical evaluation protocol conducted by nurses at HD centers.
