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

Adenosine triphosphate (ATP) is an ancient and fundamentally important biological molecule involved in both intracellular and extracellular activities. P2X ionotropic and P2Y metabotropic receptors have been cloned and characterised in mammals. ATP plays a central physiological role as a transmitter molecule in processes including the sensation of pain, taste, breathing and inflammation via the activation of P2X receptors. P2X receptors are structurally distinct from glutamate and Cys-loop/nicotinic receptors and form the third major class of ligand-gated ion channel. Yet, despite the importance of P2X receptors, both as physiological mediators and therapeutic targets, the evolutionary origins and phylogenicity of ATP signalling via P2X receptors remain unclear.
