Differences in the accumulation of phosphorus between vegetative cells and heterocysts in the cyanobacterium Nodularia spumigena.
Article in Scientific reports, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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 cyanobacterium Nodularia spumigena is a species that frequently forms blooms in the Baltic Sea. Accumulation of the vital nutrient phosphorus (P) apparently plays an important role in the ability of this and other cyanobacteria to grow even when dissolved inorganic phosphorus is depleted. However, until now, this has not been studied in N. spumigena at the cellular level. Therefore, in this study, phosphorus incorporation and distribution in cyanobacterial filaments over time was examined by scanning electron microscopy in combination with energy dispersive X-ray analysis (SEM/EDX) and nanoscale secondary ion mass spectrometry (NanoSIMS). Immediately after phosphate addition to a phosphorus-depleted population, the phosphate concentration decreased in the water while intracellular polyphosphate accumulated. Microscopically, phosphorus in form of polyphosphate granules was stored preferentially in vegetative cells, whereas heterocysts remained low in intracellular phosphorus. This information is an essential step towards understanding the phosphorus dynamics of this species and demonstrates that the division of tasks between vegetative cells and heterocysts is not restricted to nitrogen fixation.
