Permeabilizing soybean protoplasts to macromolecules using electroporation and hypotonic shock.
Article in Plant physiology, 1987. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
The percentage of soybean cell culture protoplasts permeabilized by electroporation was dependent on the voltage and the number of successive pulses that were applied. Best results were obtained with two 50 milliseconds, 400 volts per centimeter pulses after which 78% of the surviving protoplasts had been permeabilized to the fluorescent dye calcein. Quantitation of the volume of extracellular fluid taken up was performed using radioactive inulin (molecular weight 5000-5500). Typically between 20 and 40 nanoliters of fluid was taken up by 10(6) protoplasts. Electroporation and hypotonic shock treatments (M Saleem, AJ Cutler 1986 J Plant Physiol 124: 11-21) were compared with respect to the volume of fluid taken up under optimum conditions. Electroporation produced 10 times more uptake than hypotonic shock treatment. In all experiments there was a direct relationship between the number of protoplasts lysed and both the amount of fluid taken up and the percentage of surviving protoplasts that were permeabilized.
