Identification of Cartilaginous Fish Endogenous Foamy Virus Rooting to Vertebrate Counterparts.

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
Foamy viruses (FVs) are ideal models for studying the long-term evolutionary history between viruses and their hosts. Currently, FVs have been documented in nearly all major taxa of vertebrates, but evidence is lacking for true FV infiltration in cartilaginous fish, the most basal living vertebrates with jaws. Here, we screened 11 available genomes and 10 transcriptome sequence assemblies of cartilaginous fish and revealed a novel endogenous foamy virus, termed cartilaginous fish endogenous foamy virus (CFEFV), in the genomes of sharks and rays. Genomic analysis of CFEFVs revealed feature motifs that were retained among canonical FVs. Phylogenetic analysis using polymerase sequences revealed the rooting nature of CFEFVs to vertebrate FVs, indicating their deep origin. Interestingly, three viral lineages were found in a shark (Scyliorhinus torazame), one of which was clustered with ray-finned fish foamy-like viruses, indicating that multiple episodes of viral infiltrations had occurred in this species. These findings fill a major gap in the
