Investigation of bovine leukemia virus seroprevalence and transmission risk classification based on blood proviral load in beef breeding cattle in Ibaraki Prefecture, Japan.
Article in The Journal of veterinary medical science, 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
This study investigated the seroprevalence of bovine leukemia virus (BLV) in beef breeding cattle in Ibaraki, revealing a seroprevalence of 43.0% with a bimodal distribution in farms classified as either BLV-negative or very-highly infected. These results underscore the need to implement appropriate strategies for very-highly infected farms. In particular, determining the culling prioritization of cattle is absolutely necessary. It was revealed that effective control in very-highly infected farms is difficult based on types of operation or herd size. On the other hand, high-transmission-risk cattle were widely distributed across entire Ibaraki and were significantly more prevalent in very-highly infected farms. These findings suggest that the transmission risk classification is a potentially effective strategy for culling prioritization under the current circumstances in Ibaraki.
