Recurrent turnover of chromosome-specific satellites in Drosophila.
Article in Genome biology and evolution, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 25 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
Repetitive DNA are DNA sequences that are repeated multiple times in the genome and normally considered nonfunctional. Several studies predict that the rapid evolution of chromosome-specific satellites led to hybrid incompatibilities and speciation. Interestingly, in Drosophila, the X and dot chromosomes share a unique and noteworthy property: They are identified by chromosome-specific binding proteins and they are particularly involved in genetic incompatibilities between closely related species. Here, I show that the X and dot chromosomes are overpopulated by certain repetitive elements that undergo recurrent turnover in Drosophila species. The portion of the X and dot chromosomes covered by such satellites is up to 52 times and 44 times higher than in other chromosomes, respectively. In addition, the newly evolved X chromosome in D. pseudoobscura (the chromosomal arm XR) has been invaded by the same satellite that colonized the ancestral X chromosome (chromosomal arm XL), whereas the autosomal homologs in other species remain mostly devoid of satellites. Contrarily, the Müller element F in D. ananassae, homolog to the dot chromosome in D. melanogaster, has no overrepresented DNA sequences compared with any other chromosome. The biology and evolutionary patterns of the characterized satellites suggest that they provide both chromosomes with some kind of structural identity and are exposed to natural selection. The rapid satellite turnover fits some speciation models and may explain why these two chromosomes are typically involved in hybrid incompatibilities.
