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 glycine receptor mediates fast synaptic inhibition in the spinal cord and brainstem. Its activation mechanism is not known, despite the physiological importance of this receptor and the fact that it can serve as a prototype for other homopentameric channels. We analyzed single-channel recordings from rat recombinant alpha1 glycine receptors by fitting different mechanisms simultaneously to sets of sequences of openings at four glycine concentrations (10-1000 microm). The adequacy of the mechanism and the rate constants thus fitted was judged by examining how well these described the observed dwell-time distributions, open-shut correlation, and single-channel P(open) dose-response curve. We found that gating efficacy increased as more glycine molecules bind to the channel, but maximum efficacy was reached when only three (of five) potential binding sites are occupied. Successive binding steps are not identical, implying that binding sites can interact while the channel is shut. These interactions can be interpreted in the light of the topology of the binding sites within a homopentamer.
