Rapid Expansion of a Highly Germline-Expressed Mariner Element Acquired by Horizontal Transfer in the Fire Ant Genome.
Article in Genome biology and evolution, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled it.
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
Transposable elements (TEs) are present in almost all organisms and affect the host in various ways. TE activity can increase genomic variation and thereby affect host evolution. Currently active TEs are particularly interesting because they are likely generating new genomic diversity. These active TEs have been poorly studied outside of model organisms. In this study, we aimed to identify currently active TEs of a notorious invasive species, the red imported fire ant Solenopsis invicta. Using RNA profiling of male and female germline tissues, we found that the majority of TE-containing transcripts in the fire ant germline belong to the IS630-Tc1-Mariner superfamily. Subsequent genomic characterization of fire ant mariner content, molecular evolution analysis, and population comparisons revealed a highly expressed and highly polymorphic mariner element that is rapidly expanding in the fire ant genome. Additionally, using comparative genomics of multiple insect species we showed that this mariner has undergone several recent horizontal transfer events (<5.1 My). Our results document a rare case of a currently active TE originating from horizontal transfer.
