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

In comparison to globular proteins, the spontaneous folding and insertion of β-barrel membrane proteins are surprisingly slow, typically occurring on the order of minutes. Using single-molecule Förster resonance energy transfer to report on the folding of fluorescently labeled outer membrane protein G we measured the real-time insertion of a β-barrel membrane protein from an unfolded state. Folding events were rare and fast (<20 ms), occurring immediately upon arrival at the membrane. This combination of infrequent, but rapid, folding resolves this apparent dichotomy between slow ensemble kinetics and the typical timescales of biomolecular folding.
