Searching for potential Culicoides vectors of four orbiviruses in Yunnan Province, China.
Article in Parasites & vectors, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundSome species of Culicoides (Diptera, Ceratopogonidae) are major vectors for arboviruses, and Yunnan Province is a key area for arbovirus prevalence in China. Therefore, this study attempts to search for potential Culicoides vectors for the common orbiviruses bluetongue virus (BTV), epizootic hemorrhagic disease virus (EHDV), Palyam virus (PALV) and Tibet orbivirus (TIBOV) in Yunnan Province, China.
methodsCulicoides specimens were collected from 16 counties in Yunnan Province, China, using UV traps and tested for BTV, EHDV, PALV and TIBOV through one-step reverse transcription-quantitative polymerase chain reaction (RT-qPCR). A total of 543 conspecific pools of Culicoides containing 9895 specimens were tested.
resultsA total of 46 species belonging to 8 subgenera and 2 groups were recognized. A total of 19 species and a Culicoides subgenus Trithecoides complex were tested using RT-qPCR. One pool of Culicoides shortti Smith & Swaminath and one pool of Culicoides orientalis Macfie tested positive for BTV, one pool of Culicoides oxystoma Kieffer tested positive for PALV, and four pools of Culicoides jacobsoni Macfie tested positive for TIBOV. All the tested samples were negative for EHDV, and all the tested C. subgenus Trithecoides midges were negative for any virus.
conclusionsCulicoides shortti was identified as a potential BTV vector for the first time. Culicoides jacobsoni was confirmed as a potential TIBOV vector and C. orientalis as a potential BTV vector. Culicoides oxystoma was also shown to be a natural carrier of PALV using the RT-qPCR method.
