Genetic and Antigenic Characterization of Bovine and Porcine Respiratory Coronaviruses Circulating in Western Europe, 2020-2023.
Article in Viruses, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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
The 2019 coronavirus disease pandemic (COVID-19) showed how genetic mutations can alter coronavirus characteristics. However, the evolution of livestock coronaviruses remains understudied. We analyzed 15 bovine coronavirus (BCoV), three porcine hemagglutinating encephalomyelitis virus (PHEV) and 18 porcine respiratory coronavirus (PRCV) isolates, mainly from Belgian livestock collected between 2020 and 2023. Spike gene phylogenetic analysis showed nucleotide substitution rates comparable between BCoV and PRCV, while PHEV appeared slower. Unlike severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), synonymous substitutions were preferred, limiting amino acid variation across decades in the animal coronaviruses. Virus neutralization assays with swine antisera indicated minimal antigenic change in PHEV and PRCV. Recent BCoV isolates showed antigenic divergence from the classical Mebus vaccine strain. The impact of this divergence on vaccine efficacy may warrant further research. Our findings underscore the need for periodic surveillance, as changes in surface proteins may affect pathogenicity, tissue tropism, host range and vaccine efficacy.
