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

The sensation of mechanical stimuli is initiated by elastic gating springs that pull open mechanosensory transduction channels. Searches for gating springs have focused on force-conveying protein tethers such as the amino-terminal ankyrin tether of the Drosophila mechanosensory transduction channel NOMPC. Here, by combining protein domain duplications with mechanical measurements, electrophysiology, molecular dynamics simulations and modeling, we identify the NOMPC gating-spring as the short linker between the ankyrin tether and the channel gate. This linker acts as a Hookean hinge that is ten times more elastic than the tether, with the linker hinge dictating channel gating and the intrinsic stiffness of the gating spring. Our study shows how mechanosensation is initiated molecularly; disentangles gating springs and tethers, and respective paradigms of channel gating; and puts forward gating springs as core ion channel constituents that enable efficient gating by diverse stimuli and in a wide variety of channels.
