Oligomers mediate the spatial transmission of Aβ peptide aggregation.
Article in Communications chemistry, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Alzheimer's disease (AD) is marked by the abnormal aggregation of amyloid-beta peptides within the central nervous system. The formation of amyloid fibrils from amyloid-beta peptides is a hallmark of AD Here, we demonstrate that the aggregation of amyloid-beta 42 spreads both spatially and temporally. By measuring the spatial propagation of amyloid-beta in macroscopic capillaries and performing Monte Carlo simulations, we show that this spreading occurs through a diffusion mechanism involving oligomers in solution. These species, catalytically produced through spontaneous secondary nucleation, significantly accelerate the propagation velocity of the reaction wavefront. Our findings suggest that, in addition to their potential role in toxicity, these oligomers in solution are key drivers of the spatial spreading of aggregation and can therefore be considered key targets for therapeutic intervention.
