Protoplast formation of the coccolithophorid Pleurochrysis haptonemofera in hypoosmotic K+ solution: shedding of the coccosphere and regrowth of the protoplast in normal medium.
Article in Marine biotechnology (New York, N.Y.). The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Both coccolith-bearing cells (C-cells) and naked cells (N-cells) of the coccolithophorid Pleurochrysis haptonemofera can grow in salinities of more than 7 per thousand (about 20% of a "normal" sea water salinity [35 per thousand]), with the highest growth rates in salinities of more than 14 per thousand. Microscopic observations of cells suspended in 100 mM NaCl (7 per thousand) showed that, while N-cells were swelling uniformly all over the cell surface, C-cells were bulging the plasma membrane from the hole of the coccosphere at the apical (flagellar) pole of the cell. Effects of several cations and anions on the morphological change of C-cells under hypoosmotic pressure were investigated. When 100 mM K(+) was used, protoplasts were released from the coccosphere completely in almost all the cells. This phenomenon was shown with K(+) most effectively. The protoplasts could grow in the fresh medium and form the first coccolith within 9 h.
