Interventions to improve cognitive performance in chronic kidney disease: A scoping review.
Article in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
RATIONALE &
objectiveCognitive impairment is commonly associated with chronic kidney disease (CKD. A number of intervention approaches have the potential to improve cognitive performance in CKD. Our objective was to characterize interventions studied to improve cognitive performance for adults with CKD across all categories of severity, including kidney failure. STUDY
designScoping review following JBI methodology. SETTING AND STUDY POPULATIONS: Adults (≥18 years) with CKD or kidney failure. SELECTION CRITERIA FOR STUDIES: We searched 5 electronic databases for studies published up to April 5, 2024. Eligible sources were primary research studies that investigated any intervention targeting cognition in adults (≥18 years) with CKD or kidney failure. Full-text article screening was performed in duplicate. DATA EXTRACTION: Characteristics of interventions, populations studied, and outcomes investigated. ANALYTICAL APPROACH: Descriptive statistics and narrative syntheses.
resultsSeventy-one studies were included. Over half (n = 37, 52%) were conducted within the past five years, and most studies (n = 47, 66%) targeted people on maintenance hemodialysis therapy. Just over one-third of studies investigated pharmacological interventions, with much of the pharmacological or medical research focusing on anemia management or dialysis adequacy. Although recent research has expanded in focus, many other purported mechanisms of cognitive dysfunction in CKD remain understudied in interventional research. Exercise training (n = 14) was the most common nonpharmacological approach studied, but few studies have explored other promising nonpharmacological approaches such as cognitive rehabilitation interventions. LIMITATIONS: Abstract screening not performed in duplicate; non-English studies excluded.
conclusionResearch into cognitive interventions for people with kidney disease has primarily focused on the hemodialysis population and investigated erythropoietin stimulating agents, frequent or prolonged dialysis, and exercise, although there has been recent growth of research activity into other interventions. Future research should aim to address a broader range of purported pathophysiological mechanisms of cognitive impairment in CKD, investigate interventions for predialysis and peritoneal dialysis patients, and explore the impacts of established cognitive rehabilitation approaches.
