First Molecular Detection of Torque Teno Canis Virus in Apparently Healthy Dogs in Southern Italy.

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
backgroundTorque teno viruses are viruses with unclear pathogenic potential, as conflicting evidence has classified this family of viruses as harmless and opprtunistic. Dogs also have their own specific Torque teno virus, called Torque teno canis virus (TTCaV), which has been reported in several countries.
objectivesThis study aimed to identify TTCaV in the feces of apparently healthy dogs and to evaluate risk factors correlated to higher prevalences.
methodsFaecal samples were collected from 171 dogs from the Campania region, Italy. DNA was extracted from each sample and used as a template in a nested end-point PCR, and some positive samples were sequenced by the Sanger method. Univariate analysis was performed to assess the correlation between molecular detection of TTCaV and variables included in the study.
resultsA total of 18 out of 171 animals (10.5%) were PCR-positive. No individual factor (sex, age, etc.) was associated with higher prevalence, while significant differences were observed in mixed-breed (16.5%) and kennel dogs (17.7%). Although the identification of TTCaV DNA was more frequent in dogs with an altered faecal score (score > 2 on a 1-7 scale), we did not find higher prevalence in CPV-2-positive animals (even if based on only 11 CPV-2-positive samples). A total of six amplicons were sequenced, obtaining two different isolates that, once deposited in international databases and compared with those reported in other studies, showed a homology with other strains identified worldwide.
conclusionsAlthough questions concerning the clinical relevance of TTVs still remain unanswered, our study documented the presence of this virus in the dog population in southern Italy. Moreover, our work provided phylogenetic data and useful information to better characterize the epidemiological picture of this virus in Italy and in Europe.
