Methodological innovations in studying marginalized populations in research on neurodegeneration and ageing.
Review in Frontiers in aging neuroscience, 2026. 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
Underrepresented populations, often characterized by minority ethnicity, sex/gender or low socioeconomic status, have a higher risk burden and more adverse lifetime experiences of conditions negatively impacting cognitive health than better represented populations. There are several methodological challenges of research in and with marginalized populations that hinder research on improvements to their cognitive health. This review aims at presenting challenges of recruitment, data collection, and statistical analysis, and points to innovative methods for alleviating these challenges. Careful recruitment and data collection can ensure that marginalized populations are sufficiently represented in research. Multiple factors, including the clinical presentation of symptoms, accelerated biological ageing, and early life adversity need to be incorporated into statistical analysis. Innovative methodologies in research on neurodegeneration and ageing can improve the accuracy of descriptive, predictive and causal investigations, and at least partially address data inequity. These methods can contribute to the aims of reducing inequities in the distribution of healthcare and social care resources.
