1 · What the graph read from it

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.

2 · The registry

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

purposeMetabolic dysfunction-associated steatotic liver disease (MASLD) has been linked to dementia. We investigated whether liver steatosis or fibrosis is associated with early cognitive changes, while exploring related mechanisms like body mass index (BMI) and cerebral β-amyloid deposition.

methodsIn this cross-sectional study, we enrolled 26 cognitively unimpaired individuals, who underwent amyloid PET and comprehensive clinical, neurological, and neuropsychological evaluations, including the Telephone Interview for Cognitive Status (TICS). Liver steatosis and fibrosis were quantified noninvasively using vibration-controlled transient elastography (FibroScan®; Echosens, Paris, France) with an M-probe, with the controlled attenuation parameter (CAP) used to quantify liver steatosis. Multivariate regression models were used to assess relationships between liver and cognitive measures, adjusting for age.

resultsIn our cohort (mean age 72.2 ± 8.4 years), greater liver steatosis was associated with lower TICS scores, using both the CAP score (β = -0.03, p = 0.021) and steatosis grade (β = -1.39, p = 0.023). Higher liver stiffness was also negatively associated with TICS scores (β = -1.39, p = 0.042). BMI was significantly associated with greater cerebral amyloid burden (β = 9.03, p = 0.01), higher steatosis grade (β = 0.30, p = 0.03), and higher CAP scores (β = 9.47, p = 0.003).

conclusionLiver steatosis associates with lower cognitive scores in older adults. BMI associates with both steatosis and amyloid burden, which may reflect co-occurring metabolic pathways. These findings provide evidence for targeting metabolic health to preserve cognition and mitigate Alzheimer's pathology.
