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

We employ time-resolved in situ atomic force microcopy to monitor the growth of individual Aβ40 fibrils and thereby directly measure the fibril growth rates. We describe procedures to express and purify the Aβ peptide and verify its identity, prepare solutions and seeds, quantify the displacements of the growing tips of individual fibrils, and determine their respective growth rates. We discuss approaches to evaluate and minimize the impact of the scanning tip on the monitored processes. We use the distribution of fibril thickness to characterize approximately the fibril structure. The ability to quantify faithfully the growth kinetics of amyloid fibrils empowers exploration of the molecular-level processes of fibril growth that relate to behaviors of amyloid species of laboratory and clinical interest.
