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) is an intrinsically disordered peptide thought to play an important role in Alzheimer's disease (AD). It has been the target of most AD therapeutic efforts, which have repeatedly failed in clinical trials. A more predominant peptidic fragment, formed through alternative processing of the amyloid precursor protein, is the p3 peptide. p3 has received little attention, which is possibly due to the prevailing view in the AD field that it is "non-amyloidogenic." By probing the self-assembly of this peptide, we found that p3 aggregates to form oligomers and fibrils and, when compared with Aβ, displays enhanced aggregation rates. Our findings highlight the solubilizing effect of the N-terminus of Aβ and the favorable formation of structures formed through C-terminal hydrophobic peptide interfaces. Based on our findings, we suggest a reevaluation of the current therapeutic approaches targeting only the β-secretase pathway of AD, given that the α- secretase pathway is also amyloidogenic.
