Prognostic value of functional capacity assessed by the Glittre Activities of Daily Living test in hemodialysis patients: a prospective observational study.
Observational study in Jornal brasileiro de nefrologia. 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
introductionHemodialysis patients present high morbidity and mortality rates. Functional capacity has emerged as a significant marker of mortality risk across populations, and the Glittre Activities of Daily Living (Glittre-ADL) test assesses it through tasks simulating daily activities. This study aimed to investigate the prognostic value of functional capacity, as assessed by the Glittre-ADL test, in hemodialysis patients.
methodsThis was a prospective observational study conducted in a Brazilian reference hemodialysis center, involving patients aged 18 years or older who underwent dialysis three times weekly for at least three months. Baseline measurements were taken from April 2019 onward, and patients were followed until August 2024 to assess mortality. Clinical, anthropometric, and biochemical parameters were evaluated, and functional capacity was assessed through the Glittre-ADL test. Data were analyzed using Fine-Gray subdistribution hazards models, ROC curve analysis, Harrell's C-index, and Kaplan-Meier survival analysis. Cutoff values were determined, and positive and negative predictive values were calculated. Confidence intervals were estimated using bootstrap resampling (1,000 replicates).
resultsSeventy-six eligible patients were included. The median follow-up time was 38.33 (2.50-77.73) months. The Glittre-ADL test (HR: 1.003 [95%CI 1.001-1.006]; p = 0.03) and age (HR: 1.049 [95%CI 1.020-1.078]; p < 0.001) were independently associated with mortality. The optimal cutoff value for the Glittre-ADL test for identifying mortality risk was ≥268.5 seconds (AUC = 0.86; 95%CI 0.77-0.94; p < 0.0001).
conclusionsPerformance in the Glittre-ADL test was associated with prognosis and accurately identified mortality risk among hemodialysis patients.
