Drosophila euchromatic LTR retrotransposons are much younger than the host species in which they reside.

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
The recent release of the complete euchromatic genome sequence of Drosophila melanogaster offers a unique opportunity to explore the evolutionary history of transposable elements (TEs) within the genome of a higher eukaryote. In this report, we describe the annotation and phylogenetic comparison of 178 full-length long terminal repeat (LTR) retrotransposons from the sequenced component of the D. melanogaster genome. We report the characterization of 17 LTR retrotransposon families described previously and five newly discovered element families. Phylogenetically, these families can be divided into three distinct lineages that consist of members from the canonical Copia and Gypsy groups as well as a newly discovered third group containing BEL, mazi, and roo elements. Each family consists of members with average pairwise identities > or =99% at the nucleotide level, indicating they may be the products of recent transposition events. Consistent with the recent transposition hypothesis, we found that 70% (125/178) of the elements (across all families) have identical intra-element LTRs. Using the synonymous substitution rate that has been calculated previously for Drosophila (.016 substitutions per site per million years) and the intra-element LTR divergence calculated here, the average age of the remaining 30% (53/178) of the elements was found to be 137,000 +/-89,000 yr. Collectively, these results indicate that many full-length LTR retrotransposons present in the D. melanogaster genome have transposed well after this species diverged from its closest relative Drosophila simulans, 2.3 +/-.3 million years ago.
