A novel genetically distinct Amdoparvovirus in Sorex araneus in the United Kingdom highlights an unexplored ancestral link.

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
Amdoparvoviruses have historically been documented almost exclusively in carnivorans, with a few recent detections in bats and rodents. However, endogenous viral elements in rodent genomes suggest a more ancient and taxonomically broader evolutionary history. Despite this, small mammals have never been systematically surveyed for extant amdoparvovirus infections. In this study, we used whole genome sequencing to screen four different shrew species and wild American mink in the UK, which may act as a reservoir host for amdoparvoviruses. We identified a highly divergent amdoparvovirus in native common shrews (Sorex araneus) from northern England, named Shrew parvovirus 1(SP 1). Classical amdoparvovirus sequences were also detected in wild American mink (Neogale vison), confirming the presence of known amdoparvovirus strains in UK mustelids. Phylogenetic analysis revealed that the shrew virus, SP 1, forms a distinct clade, suggesting ancient divergence or long-term cryptic circulation in small mammal reservoirs. These findings provide evidence towards the hypothesis that small mammals may act as a reservoir for amdoparvoviruses and underscore the importance of systematic wildlife surveillance for understanding viral host range evolution and assessing spillover risks.
