Surveillance on African Horse Sickness Virus in China's Southern Border Regions.
Article in Transboundary and emerging diseases, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
African horse sickness (AHS) is a vector-borne and noncontagious disease caused by African horse sickness virus (AHSV) that poses a severe threat to the global equine industry. As a country historically free from AHS, China faces elevated risks due to recent outbreaks in Southeast Asia in 2020 and its ecological suitability of its border regions for AHSV vectors. Therefore, we conducted consecutive molecular and serological surveillance for AHSV in high-risk border regions from 2020 to 2024. A total of 3203 equine serum samples, 2909 whole-blood samples, and 1037 collections of blood-sucking insects were collected from 103 counties across five border provinces from June to October (peak Culicoides season). Samples were analyzed using World Organization for Animal Health (WOAH)-recommended RT-qPCR (targeting VP7 gene) and blocking ELISA. Morphological identification confirmed that the collected vectors were primarily Culicoides midges, with some mosquitoes. No AHSV nucleic acid or specific antibodies were detected, which is consistent with China's AHS-free status. Combined with predictive models and regional risk factors, the likelihood of AHSV occurrence in southern China is "likely." The study highlights the urgent need for continuous surveillance and risk assessment to safeguard China's equine industry. Further regional and ecological studies on vectors and animal transportation are also essential for understanding and mitigating the risks associated with AHSV introduction.
