Detection of PCV2d in pig industry of the Iberian Peninsula.
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 2 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
Porcine circovirus type 2 (PCV2) is a major viral pathogen affecting swine worldwide, causing significant economic losses through its association with porcine circovirus-associated diseases (PCVD), which can lead to reproductive failure, growth retardation, and increased mortality in affected herds. Although vaccination against the PCV2a and PCV2b genotypes has reduced clinical disease, the PCV2d genotype is increasingly prevalent in many regions. Molecular detection was performed on fecal samples from collected from a slaughterhouse using PCR targeting the ORF2 gene to detect PCV2 genotypes. Of 400 samples tested, 8.5% (17/200; 95% CI: 5.03-13.26) of samples from Portugal were positive for PCV2d, while none from Spain tested positive. This study reports the first confirmed detection of PCV2d in domestic pigs in Portugal in indexed journals, indicating circulation within the Portuguese swine population. The absence of PCV2 in Spanish samples may reflect differences in regional epidemiology or biosecurity practices. These findings highlight the importance of ongoing molecular surveillance and farm-level monitoring to inform vaccination strategies and control measures in response to evolving PCV2 genotypes. Integrated approaches should also consider wildlife reservoirs and environmental factors to improve management of PCV2 spread in domestic swine.
