A weakly voltage-dependent, nonselective cation channel mediates toxic sodium influx in wheat.
Article in Plant physiology, 2000. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 55 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
To determine the transporters responsible for toxic Na(+) influx in wheat (Triticum aestivum), root plasma membrane preparations were screened using the planar lipid bilayer technique as an assay for Na(+)-permeable ion channel activity. The predominant channel in the bilayer was a 44-pS channel that we called the nonselective cation (NSC) channel, which was nonselective for monovalent cations and weakly voltage dependent. Single channel characteristics of the NSC channel were compared with (22)Na(+) influx into excised root segments. Na(+) influx through the NSC channel resembled (22)Na(+) influx in its partial sensitivity to inhibition by Ca(2+), Mg(2+), and Gd(3+), and its insensitivity to all other inhibitors tested (tetraethylammonium, quinine, Cs(+), tetrodotoxin, verapamil, amiloride, and flufenamate). Na(+) influx through the NSC channel also closely resembled an instantaneous current in wheat root protoplasts (S.D. Tyerman, M. Skerrett, A. Garill, G.P. Findlay, R. Leigh [1997] J Exp Bot 48: 459-480) in its permeability sequence, selectivity for K(+) over Na(+) (approximately 1.25), insensitivity to tetraethylammonium, voltage independence, and partial sensitivity to Ca(2+). Comparison of tissue, protoplast (S.D. Tyerman, M. Skerrett, A. Garill, G.P. Findlay, R. Leigh [1997] J Exp Bot 48: 459-480), and single- channel data indicate that toxic Na(+) influx is catalyzed by a single transporter, and this is likely to be the NSC channel identified in planar lipid bilayers.
