PIGY, a new plant envelope-class LTR retrotransposon.

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
Plant LTR retrotransposons of the envelope class define a new branch in the Metaviridae family. They differ from other LTR retrotransposons mainly by the presence of an additional ORF downstream of the gag-pol region which has been hypothesized to be equivalent to the envelope gene of retroviruses. Here we present a newly identified element from pea (Pisum sativum), named PIGY, that has all the features characteristic of this group of LTR retrotransposons. In addition to the potential coding sequence downstream of the gag-pol region, PIGY has a primer binding site complementary to tRNA(asp) and a polypurine tract with a TGGGG motif and is of large size (13,645 bp). The relationship between PIGY and other retrotransposons of the env-class was confirmed by a phylogenetic analysis of their reverse transcriptase domains. One distinctive feature of PIGY is that its env-like region is actually composed of two similar ORFs, each of which encodes a protein with similarity to the Athila envelope-like protein. PIGY is present in the pea genome in 1-5x10(3) copies and is transcriptionally active, suggesting that some of these elements may still be capable of active transposition. Another new env-class retrotransposon similar to PIGY was also identified among genomic sequences of Medicago truncatula.
