The number of K(+) channels in the plasma membrane of guard cell protoplasts changes in parallel with the surface area.

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
The activity of the two dominant K(+) channels in the plasma membrane of Vicia faba guard cell protoplasts was examined during pressure-driven swelling. For this purpose, the K(+) currents and the membrane capacitance (C(m)) of guard cell protoplasts were recorded in parallel. A rise in C(m), reflecting an increase of the membrane surface area, was coupled to a proportional rise in conductance of both the K(+) inward and K(+) outward rectifier. The activation kinetics of the K(+) channels were not affected during this process. The quantitative and temporal coupling of C(m) and K(+) conductance can hence be interpreted as the result of the addition of active inward and outward rectifier K(+) channels to the plasma membrane during an increase in surface area.
