Survey of Spanish nephrologists' opinion on the applicability of Fried's geriatric frailty criteria in patients with end-stage renal disease.
Article in BMC nephrology, 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
backgroundFried described fragility as a biological syndrome in the geriatric population with 5 criteria (exhaustion, unintentional weight loss, low physical activity, slow walking speed, and poor grip strength). This diagnostic method is the most commonly used in patients with ESRD. This study aimed to analyse the opinion of Spanish nephrologists about its applicability in ESRD.
methodsA survey adapted from a Delphi used by the Johns Hopkins University School of Public Health was distributed among Spanish nephrologists, with their permission and collaboration, and with the support of the Spanish Society of Nephrology.
resultsOf the 179 respondents, 99.4% felt that frailty is prevalent in ESRD. Involuntary weight loss criterion was considered of little use by 12.5% and exhaustion by 12.6%, with consensus on the usefulness of the other three criteria. New criteria were proposed, including depression (23.5%), dependence (18.8%), cognitive impairment (16.5%), dialysis intolerance (14.1%), and malnutrition (11.8%). Intra-dialysis static pedals (74.9%) and prehabilitation in renal transplant candidates (83.1%) were considered beneficial.
conclusionsUnintentional weight loss and exhaustion were the criteria considered least appropriate for defining frailty in patients with ESRD. Future studies would be desirable to assess the applicability of the proposed new criteria and the efficacy of intervention and prehabilitation measures. CLINICAL TRIAL NUMBER: Not applicable.
