Atomic Structure of GNNQQNY Nanocrystals: A Validated Approach for Polymorphic Amyloids.
Article in The journal of physical chemistry letters, 2025. 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
Magic angle spinning (MAS) nuclear magnetic resonance (NMR) is a powerful tool for determining the structures of complex biological systems like amyloid fibrils, which are often challenging to study due to polymorphism. However, traditional MAS NMR techniques are often limited by low signal-to-noise ratios (SNR) for long-range distances and by spectral overlap in degenerate systems. Here we establish an approach to address these challenges using the amyloid heptapeptide GNNQQNY, an ideal model for studying polymorphism due to its ability to assemble into either crystals or fibrils depending on preparation conditions. By employing specific
