Low- and high-affinity reactions in rapid neurotransmission.
Review in Neurochemical research, 2003. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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.
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
Until 1950-1960, most physiologists were reluctant to accept chemical neurotransmission. They believed that chemical reactions were much too slow to account for the speed of synaptic processes. The first breakthrough was to discover the impressive velocity of acetylcholinesterase. Then, nicotinic receptors provided an example of complex ultrarapid reactions: fast activation at a low ligand affinity, then desensitization if the ligand is not rapidly removed. Here, we describe synaptic transmission as a chain of low-affinity rapid reactions, assisted by many slower regulatory processes. For starting quantal acetylcholine release, mediatophores are activated by high Ca2+ concentrations, but they desensitize at a higher affinity if Ca2+ remains present. Several mechanisms concur to the rapid removal of Ca2+ from the submembrane microdomains. Among them, the Ca2+/H+ antiport is a typical low-affinity, high-speed process that certainly contributes to the rapidity of neurotransmission.
