Construction and analysis of a modified transposable element carrying an outward directed inducible promoter for Bacillus subtilis.
Article in Current microbiology, 2014. 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
Transposons are important tools to inactivate chromosomal genes followed by a correlation with a particular phenotype or genotype. Here we demonstrated the development of a special type of genetically engineered transposon carrying an outward-directed inducible promoter in order to allow transcription of nearby genes. We have modified the mariner transposon TnYLB able to transpose in B. subtilis. This modified TnYLB carries an expression unit consisting of the xylose repressor xylR and an outward-directed promoter negatively controlled by this repressor. This TnYLB-XylOut transposon is able to turn on gene expression if insertion occurs close to a promoter-less gene. It will be an important tool to identify the function of genes either by turning on their expression or by enhanced expression depending on the xylose concentration.
