Internal deletions of transposable elements: the case of Lemi elements.
Article in Genetica, 2013. 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
Mobile elements using a "cut and paste" mechanism of transposition (Class II) are frequently prone to internal deletions and the question of the origin of these copies remains elusive. In this study, we looked for copies belonging to the Lemi Family (Tc1-mariner-IS630 SuperFamily) in the plant genomes, and copies within internal deletions were analyzed in detail. Lemi elements are found exclusively in Eudicots, and more than half of the copies have been deleted. All deletions occur between microhomologies (direct repeats from 2 to 13 bp). Copies less than 500 bp long, similar to MITEs, are frequent. These copies seem to result from large deletions occurring between microhomologies present within a region of 300 bp at both extremities of the element. These regions are particularly A/T rich, compared to the internal part of the element, which increases the probability of observing short direct repeats. Most of the molecular mechanisms responsible for double strand break repair are able to induce deletions between microhomologies during the repair process. This could be a quick way to reduce the population of active copies within a genome and, more generally, to reduce the overall activity of the element after it has entered a naive genome.
