Gypsy, RTE and Mariner transposable elements populate Eyprepocnemis plorans genome.
Article in Genetica, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 22 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
We analyze here the presence and abundance of three types of transposable elements (TEs), i.e. Gypsy, RTE and Mariner, in the genome of the grasshopper Eyprepocnemis plorans. PCR experiments allowed amplification, cloning and sequencing of these elements (EploGypI, EploRTE5, EploMar20) from the E. plorans genome. Fluorescent in situ hybridization (FISH) showed that all three elements are restricted to euchromatic regions, thus being absent from the pericentromeric region of all A chromosomes, which contain a satellite DNA (satDNA) and ribosomal DNA (rDNA), and being very scarce in B chromosomes mostly made up of these two types of repetitive DNA. FISH suggested that EploGypI is the most abundant and EploMar20 is the least abundant, with EploRTE5 showing intermediate abundance. An estimation of copy number, by means of quantitative PCR, showed that EploGypI is, by far, the most abundant element, followed by EploRTE5 and EploMar20, in consistency with FISH results. RNA isolation and PCR experiments on complementary DNA (cDNA) showed the presence of transcripts for the three TE elements. The implications of the preferential location of these TE elements into euchromatin, the significance of TE abundance in the giant genome of this species, and a possible relationship between TEs and B chromosome mutability, are discussed.
