LINE-1 distribution in Afrotheria and Xenarthra: implications for understanding the evolution of LINE-1 in eutherian genomes.
Article in Chromosoma, 2004. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 28 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
Long interspersed nuclear elements (LINEs) comprise about 21% of the human genome (of which L1 is most abundant) and are preferentially accumulated in AT-rich regions, as well as the X and Y chromosomes. Most knowledge of L1 distribution in mammals is restricted to human and mouse. Here we report the first investigation of L1 distribution in the genomes of a wide variety of eutherian mammals, including species in the two basal clades, Afrotheria and Xenarthra. Our results show L1 accumulation on the X of all eutherian mammals, an observation consistent with an ancestral involvement of these elements in the X-inactivation process (the Lyon repeat hypothesis). Surprisingly, conspicuous accumulation of L1 in AT-rich regions of the genome was not observed in any species outside of Euarchontoglires (represented by human, mouse and rabbit). Although several features were common to most species investigated, our comprehensive survey shows that the patterns observed in human and mouse are, in many aspects, far from typical for all mammals. We discuss these findings with reference to models that have previously been proposed to explain the AT distribution bias of L1 in human and mouse, and how this relates to the evolution of these elements in other eutherian genomes.
