Helitrons and Retrotransposons Are Co-localized in
Article in Current genomics, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundDNA transposons helitrons are mobile genetic elements responsible for major movements of the genetic material within and across different genomes. This ability makes helitrons suitable candidate elements for the development of new approaches of multilocus genotyping of live-stock animals, along with the well-known microsatellite loci.
objectiveWe aimed to estimate the informativeness of helitron and microsatellite markers in assessing the consolidation and the "gene pool" standards of two commercial dairy cattle breeds (Ayrshire breed and holsteinized Black-and-White cattle) and one local breed of Kalmyk cattle, and to reveal any inter-breed difference in the organization of genomic regions flanked by helitrons in the studied cattle breeds.
methodWe used the combination of two highly-polymorphic genomic elements - helitrons and trinu-cleotide microsatellites (AGC)6G and (GAG)6C, respectively - for genome scanning of the sampled groups of cattle. Also, we pyrosequenced the genomic regions flanked by the inverted repeats of 3'-end of Heligloria family of helitron fragments.
resultsGenerally, the both combinations of markers generated polymorphic spectra, based on which certain interbreed differentiation could be observed. The analysis of the identified interspersed repeats suggests that in factory and local cattle the genomic regions flanked by helitron fragments are shaped differently and contain different superfamilies of transposable elements, especially retrotransposons.
conclusionDespite the well-known fact of retrotransposon-dependent microsatellite expansion, our data suggest that, in the cattle genome, the DNA transposons and microsatellites can also be found in close neighbourhood, and that helitrons and retrotransposons may form domains of increased variability - targets for factors of artificial selection.
