Genetic shifts of Japanese encephalitis virus (JEV) in mosquitoes in the Republic of Korea, 2017-2022.
Article in PLoS neglected tropical diseases, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
backgroundThe Japanese encephalitis virus (JEV) is transmitted by mosquitoes and circulates in Asia, the western Pacific, and other parts of the world. It is classified into five genotypes (GI-GV) based on the nucleotide sequence of the envelope (E) gene. Despite extensive surveillance, shifts in genotype distribution and mosquito species remain underreported, particularly in the Republic of Korea. METHODOLOGY/PRINCIPAL
findingsWe conducted a nationwide mosquito collection from 2017 to 2022, capturing 1,102,031 mosquitoes from 32 sites nationwide. The predominant species were Aedes vexans (34.2%), Culex pipiens (17.9%), Cx. tritaeniorhynchus (13.4%), Ae. albopictus (4.0%), and Cx. orientalis (0.6%). JEV was detected in 49 pools, with the majority from Cx. pipiens and Cx. tritaeniorhynchus. Genetic analyses identified genotypes I, III, and V, with genotype V becoming dominant from 2020 onwards. CONCLUSIONS/SIGNIFICANCE: The emergence of genotype V as the dominant strain of the JEV, along with its detection in mosquito species other than the previously known Cx. tritaeniorhynchus, highlights the need for ongoing surveillance. These findings underscore the importance of developing vaccines effective against all JEV genotypes to mitigate public health risks.
