Discovery of Novel Viruses and Common Contaminants From Unmapped DNA and RNA in Pigs and Chickens Under Different Housing Conditions.
Article in Animal genetics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Unmapped sequencing reads in livestock often contain valuable information about pathogens but are typically discarded. We analyzed blood-derived DNA and RNA from chickens and pigs kept under high- and low-biosecurity conditions, focusing on unmapped reads. In chickens, low-biosecurity farms harbored substantially more viral sequences, primarily plant viruses, indicating environmental contamination. In pigs, Mycoplasmoides pneumoniae and several pig-specific viruses were detected. Our bioinformatics pipeline, involving host read removal, assembly, BLAST, and taxonomic filtering, efficiently identified candidate pathogens and contaminants. This approach demonstrates the potential of sequencing-based environmental DNA monitoring to track microbial and viral presence, assess farm biosecurity, and support animal health surveillance.
