GalEa retrotransposons from galatheid squat lobsters (Decapoda, Anomura) define a new clade of Ty1/copia-like elements restricted to aquatic species.

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
Crustacean species have not been examined in great detail for their transposable elements content. Here we focus on galatheid crabs, which are one of the most diverse and widespread taxonomic groups of Decapoda. Ty1/copia retrotransposons are a diverse and taxonomically dispersed group. Using degenerate primers, we isolated several DNA fragments that show homology with Ty1/copia retroelements reverse transcriptase gene. We named the corresponding elements from which they originated GalEa1 to GalEa3 and analyzed one of them further by isolating various clones containing segments of GalEa1. This is the first LTR retrotransposon described in crustacean genome. Nucleotide sequencing of the clones revealed that GalEa1 has LTRs (124 bp) and that the internal sequence (4,421 bp) includes a single large ORF containing gag and pol regions. Further screening identified highly related elements in six of the nine galatheid species studied. By performing BLAST searches on genome databases, we could also identify GalEa-like elements in some fishes and Urochordata genomes. These elements define a new clade of Ty1/copia retrotransposons that differs from all other Ty1/copia elements and that seems to be restricted to aquatic species.
