First detection of atypical porcine pestivirus in piglets affected by congenital tremor in Poland.
Article in Veterinary research communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Congenital tremors are neurological disorders of newborn piglets that may lead to serious health consequences, including increased mortality. Many reports have indicated that atypical porcine pestivirus (APPV), first identified in 2015, is a possible cause of this condition. In different countries, APPV was detected in farms affected by piglets' congenital tremors. There is a lack of data regarding the presence of this virus in Poland. However, swine veterinarians report outbreaks of congenital tremor with unestablished aetiology nationwide. Therefore, this study aimed to verify the presence of APPV in piglets with congenital tremors in Poland. Samples of blood (2), faecal swabs (7), brain (7), cerebellum (5), spinal cord, (7) lymph nodes (7), tonsil (7), thymus (6), tongue (7), heart (7), lung (7) and liver (7) were collected from piglets. Form sows' blood (5) and oral fluid (3, pooling samples) were collected. All samples have been derived from a commercial breeding farm reporting a case of congenital tremor and subjected to the qPCR via commercial kit (EXOone Atypical Porcine Pestivirus, Exopol, Spain). Six out of seven piglets tested positive for APPV, with the highest viral loads detected in the cerebellum and tonsils. All samples from sows were negative, emphasising the virus's specificity to piglets. To the authors' knowledge, this is the first report confirming APPV's presence in Poland. Given the potentially significant impact of APPV infections on swine health and production economics, further research evaluating the epidemiology and pathogenicity of APPV, as well as identifying preventive measures, is sorely needed.
