Toxic effects induced by salt stress on selected freshwater prokaryotic and eukaryotic microalgal species.
Article in Ecotoxicology (London, England), 2009. 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
In order to determine the short-term impact induced by salt stress, cultures of Dictyosphaerium chlorelloides and Microcystis aeruginosa were grown in presence of increasing sea-salt concentrations. Growth rate and photosystem II activity in D. chlorelloides, and photosynthetic oxygen production (in both species) were analyzed. A concentration-dependent response was obtained with the presence of sea-salt in culture medium, being M. aeruginosa (EC(50(72)) = 76.6 mM) more sensitive to salt stress than D. chlorelloides (EC(50(72)) = 340.7 mM). However, comparative analysis between growth and Phi(PSII) inhibition in D. chlorelloides shown that there are not significant differences among EC(50(72)) values obtained. An immediate toxic response, induced by increase of sea-salt concentration, has been obtained applying the calculated EC(50(72)) values in both species. These results shown that sea-salt acts as a sensitive and rapid toxic compound in algal cells, and that the sensitivity of M. aeruginosa to salinity stress is much higher than that of D. chlorelloides.
