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

Current therapeutic approaches under development for Alzheimer disease, including γ-secretase modulating therapy, aim at increasing the production of Aβ(1-38) and Aβ(1-40) at the cost of longer Aβ peptides. Here, we consider the aggregation of Aβ(1-38) and Aβ(1-43) in addition to Aβ(1-40) and Aβ(1-42), in particular their behavior in mixtures representing the complex in vivo Aβ pool. We demonstrate that Aβ(1-38) and Aβ(1-43) aggregate similar to Aβ(1-40) and Aβ(1-42), respectively, but display a variation in the kinetics of assembly and toxicity due to differences in short timescale conformational plasticity. In biologically relevant mixtures of Aβ, Aβ(1-38) and Aβ(1-43) significantly affect the behaviors of Aβ(1-40) and Aβ(1-42). The short timescale conformational flexibility of Aβ(1-38) is suggested to be responsible for enhancing toxicity of Aβ(1-40) while exerting a cyto-protective effect on Aβ(1-42). Our results indicate that the complex in vivo Aβ peptide array and variations thereof is critical in Alzheimer disease, which can influence the selection of current and new therapeutic strategies.
