Evolution of P elements in natural populations of Drosophila willistoni and D. sturtevanti.
Article in Genetics, 2004. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
To determine how population structure of the host species affects the spread of transposable elements and to assess the strength of selection acting on different structural regions, we sequenced P elements from strains of Drosophila willistoni and Drosophila sturtevanti sampled from across the distributions of these species. Elements from D. sturtevanti exhibited considerable sequence variation, and similarity among them was correlated to geographic distance between collection sites. By contrast, all D. willistoni elements sampled were essentially identical (pi < 0.2%) and exhibited patterns typical of a recent population expansion. While the canonical P elements sampled from D. sturtevanti appear to be long-time residents in that species, a rapid expansion of a very young canonical P-element lineage is suggested in D. willistoni, overcoming barriers such as large geographical distances and moderate levels of population subdivision. Between-species comparisons reveal selective constraints on P-element evolution, as indicated by significantly different substitution rates in noncoding, silent, and replacement sites. Most remarkably, in addition to replacement sites, selection pressure appears to be strong in the first and third introns and in the 3' and 5' flanking regions.
