Prevalence and factors associated with frailty among incident kidney transplant patients: a cross-sectional study.
Article in Sao Paulo medical journal = Revista paulista de medicina, 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
backgroundEvidence on frailty prevalence in Brazilian patients with kidney transplant (KT) is scarce.
objectivesTo estimate frailty prevalence in pre-KT patients and its association with functional, cognitive, and laboratory anomalies. DESIGN AND
settingCross-sectional descriptive study included adult KT candidates assessed within 24 hours before KT, at two medical centers in Northeast Brazil.
methodsFrailty was classified as non-frail (scores 0-1), intermediate frail (score 2), or frail (scores 3-5), using Fried et al. criteria. Patients were divided into: Non-frail (0-1) and Frail (≥ 2) groups. Katz and Lawton's scales assessed the dependence on basic (ADLs) and instrumental (IADLs) activities of daily living, respectively. Montreal Cognitive Assessment was used to evaluate cognition. Laboratory tests were performed during pre-KT evaluation.
resultsAmong 82 patients, most were male (80.5%), mixed-race (76.8%), and 48.8 ± 14.9-years-old. The Frail group (63.4%) comprised 34.1% intermediate frail, and 29.3% frail individuals. This group had a higher prevalence of hypertension (90.4% vs. 70%, P = 0.018), rheumatological diseases (15.4% vs. 0%, P = 0.024), cognitive impairment (71.0% vs. 40.7%, P = 0.020), dependence on ADLs (32% vs. 0%, P < 0.001) and IADLs (82% vs. 56.7%, P = 0.014), lower hemoglobin (11.9 ± 2.7 g/dL vs. 13.4 ± 1.8 g/d, P = 0.005), and lower creatinine levels (7.1 mg/dL, IQR 6-10 vs. 9.1 mg/dL, IQR 7-11, P = 0.044).
conclusionsPretransplant frailty was prevalent and associated with functional disability, cognitive impairment, and biomarkers indicating sarcopenia. Early frailty assessment and identification of modifiable factors are essential.
