Pseudorabies virus in wild swine: current evidence and interpretations from monitoring studies.
Synthesis in BMC 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
To synthesize current knowledge on pseudorabies virus (PRV; also known as Aujeszky's disease virus or Suid alphaherpesvirus 1) infections in wild swine, a combined review and meta-analysis was conducted. The study aimed to critically interpret reported PRV seroprevalence data, assess risks for animal health and disease control programs, and inform future monitoring and management strategies. An extensive literature search covering the period from 1970 to 2025 identified 160 serosurveys published between 1979 and 2024, yielding 516 datasets for analysis. Binomial logistic and mixed-effects logistic regression models were used to assess spatio-temporal patterns. The results indicate that PRV is widely established in wild swine populations, particularly in Europe and North America, forming stable endemic cycles largely independent of host density. Persistent spatial heterogeneity and region-specific temporal trends were observed, and once introduced into naïve populations, PRV appears to persist long term, limiting the added value of continued monitoring in long-established endemic areas.
