High incidence of interchromosomal transpositions in the evolutionary history of a subset of or genes in Drosophila.
Article in Journal of molecular evolution, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
In insects, the odorant receptor (Or) multigene family is an intermediate-sized family with genes present in all chromosomes, indicating that duplication followed by interchromosomal transposition played an important role in the early stages of the family evolution. Here, we have explored the occurrence of interchromosomal transpositions in more recent stages through the comparative analysis of a subset of Or genes in Drosophila, where the gene content of chromosomal arms is highly conserved. The studied subset consisted of 11 Or genes located on the left arm of chromosome 3 (Muller's D element) in D. melanogaster. Our study focused on the number and chromosomal arm location of these members of the family across the 12 Drosophila species with complete genome sequences. In contrast to previous results from in situ hybridization comparative mapping that were mainly based on single-copy genes, our study, based on members of a multigene family of moderate size, revealed repeated interchromosomal transposition events and a complex history of some of the studied genes.
