Effect of the amino acid substitution in the DNA-binding domain of the Fur regulator on production of pyoverdine.
Article in Folia microbiologica, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 ferric uptake regulator gene (fur), its promoter region and Fur box of pvdS gene involved in siderophore-mediated iron uptake system were sequenced in the parent strain Pseudomonas aeruginosa PAO1 and in the fur mutant FPA121 derived from the strain PAO1. We identified the gene fur 179 bearing a novel, single-point mutation that changed the amino acid residue Gln60Pro in the DNA-binding domain of the Fur protein. The synthesis of pyoverdine was studied in cultures of the strains PAO1 and FPA121 grown in iron-deplete and iron-replete (60 μmol/L FeIII) medium. The amino acid replacement in the regulatory Fur protein is responsible for the overproduction of pyoverdine in iron-deplete and iron-replete medium. No mutation was identified in the Fur box of the gene pvdS.
