Evaluation of the regulatory model for Ni
Article in Journal of inorganic biochemistry, 2020. 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
Streptomyces coelicolor is a soil-dwelling bacterium that is medically important due to its ability to produce several antibiotics, and nickel accumulation within this organism has been shown to prevent the production of the antibiotic undecylprodigiosin. The transcriptional repressor important in regulation of nickel uptake is the homodimeric Nur, a member of the Fur family. Nur contains two metal-binding sites per monomer: the M-site and the Ni-site. The work described here seeks to determine the roles of each of the metal-binding sites to establish a model of Nur activity through mutational studies, metal titrations, and fluorescence anisotropy. Through these studies, a model of Nur activity is proposed in which femtomolar metal binding to one M-site of Nur prompts DNA-binding, and metal binding to the second M-site fully activates the protein. Evidence is provided that shows cooperative metal binding to the Ni-site, but this process dampens affinity for promoter DNA.
