Blood lipids as accessible biomarkers for early dementia risk screening: Bridging diagnostic gaps in resource-limited settings.
Review in Journal of Alzheimer's disease reports. 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
Background: Dementia prevalence is rising globally, with the greatest increase occurring in low- and middle-income countries where access to advanced diagnostic tools remains limited. Circulating lipid parameters have been increasingly investigated as accessible biomarkers for dementia risk and cognitive decline. Objective: To systematically review and synthesize existing evidence on the relationship between circulating lipid parameters and dementia risk, Alzheimer's disease, and cognitive decline, with particular consideration of their potential utility in resource-limited settings. Methods: A systematic literature review was conducted in accordance with PRISMA guidelines. Studies published between 2000 and May 2025 evaluating associations between lipid profiles and cognitive outcomes, dementia, or neurodegenerative disease were included and narratively synthesized. Results: Evidence across studies suggests that lipid dysregulation is associated with dementia-related outcomes, although findings remain heterogeneous. Elevated total cholesterol, low-density lipoprotein cholesterol, and triglycerides were frequently associated with increased risk of dementia, Alzheimer's disease, or cognitive decline, whereas high-density lipoprotein cholesterol generally showed protective associations. Several studies also identified prognostic value in composite lipid ratios and lipid variability measures. However, the strength and direction of associations varied according to age, sex, timing of lipid assessment, and study population. Conclusions: Circulating lipid parameters alone are insufficient as definitive diagnostic biomarkers. However, when interpreted in a population-specific and life-course context, they may contribute to early risk stratification and complement neuropsychological screening, particularly in resource-limited settings where access to advanced neuroimaging and cerebrospinal fluid testing is restricted.
