Envelope-class retrovirus-like elements are widespread, transcribed and spliced, and insertionally polymorphic in plants.
Article in Genome research, 2001. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 40 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 and retroviruses share similar intracellular life cycles and major encoded proteins, but retrotransposons lack the envelope (env) critical for infectivity. Retrotransposons are ubiquitous and abundant in plants and active retroviruses are known in animals. Although a few env-containing retroelements, gypsy-like Athila, Cyclops, and Calypso and copia-like SIRE-1, have been identified in plants, the general presence and functionality of the domain remains unclear. We show here that env-class elements are present throughout the flowering plants and are widely transcribed. Within the grasses, we show the transcription of the env domain itself for Bagy-2 and related retrotransposons, all members of the Athila group. Furthermore, Bagy-2 transcripts undergo splicing to generate a subgenomic env product as do those of retroviruses. Transcription and the polymorphism of their insertion sites in closely related barley cultivars suggests that at least some are propagationally active. The putative ENV polypeptides of Bagy-2 and rice Rigy-2 contain predicted leucine zipper and transmembrane domains typical of retroviral ENVs. These findings raise the prospect of active retroviral agents among the plants.
