Porcine circovirus 4 status of domestic pigs and wild animals in Poland.
Article in Journal of veterinary research, 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
Introduction: Given the threat that porcine circovirus (PCV) 2 and PCV3 pose to the pig industry, the epidemiology of emerging PCV4 warrants further investigation. Until 2023, PCV4 had only been confirmed in Asia, with the majority of reports originating from China. More recently, PCV4 DNA has also been detected in samples from Spain and the United States, indicating a potentially broader geographic distribution. Furthermore, PCV4 DNA has been identified in samples from other animal species. This study aimed to evaluate the presence of PCV4 in samples collected from domestic pigs, wild boars and wild ruminants in Poland using its Material and Methods: A total of 474 serum samples from domestic pigs and 226 blood and internal organ samples (lymph nodes, spleen and lungs) from 20 wild boars, 33 fallow deer, 4 red deer and 6 roe deer were tested using qPCR to detect the presence of PCV4 DNA. Results: No PCV4 was detected in any of the samples. Conclusion: The presence of PCV4 in other populations or regions of Poland cannot be excluded. Further research is needed to monitor the epidemiological situation in the country, particularly in light of emerging reports confirming the presence of the virus in Europe.
