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

Acid sensing is essential for various biological processes in animals, yet it exhibits species-specific characteristics. In this study, we identified a proton-dissociation-permeated sodium channel (PDPNaC1) in the antennal sensory neurons of the centipede Scolopendra subspinipes mutilans. PDPNaC1, which is permeable to monovalent cations, assembles as a homotrimer. Unlike most proton-gated channels, where proton binding induces currents, PDPNaC1's transient ion-permeable state is triggered by proton dissociation. By resolving the high-resolution cryo-electron microscopy (cryo-EM) structure of PDPNaC1, combined with mutagenesis and electrophysiological analyses, we identified Gly378, rather than the Gly-Ala-Ser tract, as a key determinant of ion selectivity. Furthermore, Ser376, located in the ion-permeable pathway, likely serves as a proton-binding site, leading to an H
