Lower estimated glomerular filtration rate relates to cognitive impairment and brain alterations.
Article in Alzheimer's & dementia (Amsterdam, Netherlands). The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
introductionChronic kidney disease (CKD) is associated with cognitive decline and changes in brain structure. However, their associations remain unclear, particularly the selective vulnerability characteristics that make some brain regions more vulnerable.
methodsWe investigated the baseline association between estimated glomerular filtration rates (eGFR) and cognitive function in 15,897 individuals from the CARTaGENE cohort. We performed vertex-based magnetic resonance imaging (MRI) analyses between eGFR and longitudinal cortical thickness in the 1397 participants who underwent brain MRI after 6 years. Imaging transcriptomics was used to characterize the gene expression and neurodegenerative features associated with this association.
resultsLower eGFR correlated with reduced cognitive performance and brain structure. Brain regions associated with eGFR were enriched for mitochondrial and inflammatory-related genes. These associations occurred independently from age, sex, education, and body mass index (BMI), Framingham risk score, and white matter lesion volume. DISCUSSION: This study highlights the link between reduced eGFR, cognitive impairment, and brain structure, revealing some of the kidney-brain axis mechanisms. Highlights: Lower eGFR is associated with reduced cognitive abilities.Structural brain changes are mediated by eGFR levels.Specific gene expression patterns correlate with lower eGFR and brain changes.Mitochondrial and inflammation-related genes were enriched in these patterns.
