Transient interactions between the fuzzy coat and the cross-β core of brain-derived Aβ42 filaments.
Article in Science advances, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Several human disorders, including Alzheimer's disease (AD), are characterized by the aberrant formation of amyloid fibrils. In many cases, the amyloid core is flanked by disordered regions, known as fuzzy coat. The structural properties of fuzzy coats, and their interactions with their environments, however, have not been fully described to date. Here, we generate conformational ensembles of two brain-derived amyloid filaments of Aβ42, corresponding respectively to the familial and sporadic forms of AD. Our approach, called metadynamic electron microscopy metainference (MEMMI), provides a characterization of the transient interactions between the fuzzy coat and the cross-β core of the filaments. These calculations indicate that the familial AD filaments are less soluble than the sporadic AD filaments, and that the fuzzy coat contributes to solubilizing both types of filament. These results illustrate how the metainference approach can help analyze cryo-EM maps for the characterization of the properties of amyloid fibrils.
