Seroprevalence of West Nile, Usutu and tick-borne encephalitis viruses in equids from south-western France in 2023.
Article in Veterinary research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 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 circulation of West Nile virus (WNV), Usutu virus (USUV), and tick-borne encephalitis virus (TBEV) was investigated in south-western France during the first six months of 2023, following the emergence of WNV in equids in Gironde, a département in south-western France, in 2022. Blood samples were collected from 494 horses located in the Gironde département and divided into three zones: the Confluence zone, the Intermediate zone and the Arcachon Basin. Samples were tested for WNV-, USUV- and TBEV-specific antibodies. An overall seroprevalence of 14% (95% CI [11-18%]) for orthoflavivirus antibodies was detected in Gironde. The highest seroprevalence rates for WNV and USUV were observed in the Confluence Zone (9%, 95% CI [6-13%] and 5%, 95% CI [3-8%], respectively), where the type of housing (animals kept in pasture only) and proximity to a special bird protection area were identified as risk factors for WNV seropositivity. This study presents the first seroprevalence investigation of WNV, USUV and TBEV infections in equids located on the Atlantic coast of France and demonstrates intense circulation of WNV in this region, as well as evidence of equine USUV-specific infection.
