Potassium channels of adult locust (Schistocerca gregaria) muscle.
Article in Pflugers Archiv : European journal of physiology, 1996. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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
Two types of K+ channels have been identified in patches of plasma membrane of metathoracic extensor tibiae muscle fibres of adult locust, Schistocerca gregaria. One channel had a maximum conductance of 170 pS, fast open-closed kinetics, and a linear current/ voltage relationship. In inside-out patches it was activated by "internally applied" Ca2+, but at unexpectedly low levels (between 10(-10) and 10(-9)M). The other channel had a maximum conductance of 35 pS, slower open-closed kinetics, and was not activated by Ca2+. In cell-attached patches, its channel conductance measured in symmetrical salines was about three times greater for hyperpolarisations than for depolarisations. This inward rectification was proved to be due to block by intracellular Mg2+. For both channels, open probability (Po) and mean open time increased during depolarisations and decreased during hyperpolarisations, resulting in outward rectifications in terms of net current (I n, product of the single-channel current and Po). For both channels, the K+ conductance was 10 times greater than that for Na+. Internally applied tetraethylammonium or tetramethylammonium ions blocked both channels.
