1 · What the graph read from it

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.

2 · The registry

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

Amyloid-β (Aβ) fibrils are considered key pathological agents in the progression of Alzheimer’s disease. Recent studies demonstrated that N-(2-hydroxyethyl)piperazine-N’-(3-propane-sulfonic acid) (EPPS) effectively disaggregates Aβ oligomers and plaques in the brains of APP/PS1 transgenic mice, though its molecular mechanism remains unclear. In this study, we investigated the disaggregation mechanism of Aβ fibrils by EPPS using replica-exchange molecular dynamics (REMD) simulations. Our results showed that EPPS preferentially binds to the exterior strands of Aβ fibrils, particularly interacting with Glu22 residues via ionic interactions. This binding induced significant structural fluctuations, which propagated to neighboring strands in a time-dependent manner. Clustering analysis revealed that EPPS disrupts intermolecular hydrogen bonding at the fibril edge, destabilizing the β-strand structure. Secondary structure analysis further confirmed a decrease in β-sheet content in the exterior segments. These findings provide molecular-level insights into the dissociation mechanism of Aβ fibrils by EPPS and suggest potential strategies for developing anti-amyloid therapeutics.
