The non-regular orbit: three satellite DNAs in Drosophila martensis (buzzatii complex, repleta group) followed three different evolutionary pathways.

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 genome of species from the buzzatii cluster (buzzatii complex, repleta group) is hosted by a number of satellite DNAs (satDNAs) showing contrasting structural characteristics, genomic organization and evolution, such as pBuM-alpha (~190 bp repeats), pBuM-alpha/beta (~370 bp repeats) and the DBC-150 (~150 bp repeats). In the present study, we aimed to investigate the evolution of these three satDNAs by looking for homologous sequences in the genome of the closest outgroup species: Drosophila martensis (buzzatii complex). After PCR, we isolated and sequenced 9 alpha, 8 alpha/beta and 11 DBC-150 sequences from this species. The results were compared to all pBuM and DBC-150 sequences available in literature. After D. martensis split from the buzzatii cluster some 6 Mya, the three satDNAs evolved differently in the genome of D. martensis by: (1) maintenance of a collection of major types of ancestral repeats in the genome (alpha); (2) fixation for a single major type of ancestral repeats (alpha/beta) or (3) fixation for new divergent species-specific repeat types (DBC-150). Curiously, D. seriema and D. martensis, although belonging to different and allopatric clusters, became independently fixed for the same major type of alpha/beta ancestral repeats, illustrating a rare case of parallelism in satDNA evolution. The contrasting pictures illustrate the diversity of evolutionary pathways a satDNA can follow, defining a "non-regular orbit" with outcomes difficult to predict.
