Tmt1: the first LTR-retrotransposon from a Tuber spp.
Article in Current genetics, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
Retrotransposons are suitable targets for developing molecular markers for population genetics studies. Transposable elements have not yet been isolated from ectomycorrhizal fungi of the genus Tuber. In this paper, we report on the isolation and characterization of Tmt1, an LTR-retrotransposon from Tuber melanosporum. The Tmt1 sequence shows relatedness to Ty3/gypsy retrotransposons from which it differentiates for the presence of a dUTPase extra-domain between protease and reverse transcriptase. Phylogenetic analyses suggest a horizontal transfer of the dUTPase gene (dut) from a fungal host genome. The presence of non-identical LTRs and degenerate ORFs substantiate an ancient integration of Tmt1 in T. melanosporum genome. Furthermore, transcripts analyses proved an inactive status of Tmt1, whereas Southern analysis showed that Tmt1 is a repetitive T. melanosporum species-specific element. Tmt1-based markers will help us to gain more insights into population biology in this fungal species.
