Rapid evolution of two odorant-binding protein genes, Obp57d and Obp57e, in the Drosophila melanogaster species group.
Article in Genetics, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 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
Genes encoding odorant-binding protein (OBP) form a large family in an insect genome. Two OBP genes, Obp57d and Obp57e, were previously identified to be involved in host-plant recognition in Drosophila sechellia. Here, by comparing the genomic sequences at the Obp57d/e locus from 27 Drosophila species, we found large differences in gene number between species. Phylogenetic analysis revealed that Obp57d and Obp57e in the D. melanogaster species group arose by gene duplication of an ancestral OBP gene that remains single in the obscura species group. Further gain and loss of OBP genes were observed in several lineages in the melanogaster group. Site-specific analysis of evolutionary rate suggests that Obp57d and Obp57e have functionally diverged from each other. Thus, there are two classes of gene number differences in the Obp57d/e region: the difference of the genes that have functionally diverged from each other and the difference of the genes that appear to be functionally identical. Our analyses demonstrate that these two classes of differences can be distinguished by comparisons of many genomic sequences from closely related species.
