Real-world effectiveness of EV-A71 vaccine against encephalitis in children.
Article in Human vaccines & immunotherapeutics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
While the EV-A71 vaccine is available, its real-world effectiveness against severe neurological complications such as encephalitis and its influence on circulating enterovirus serotypes require further clarification. This single-center, retrospective study analyzed 7823 children hospitalized with enterovirus-associated hand, foot, and mouth disease or herpangina between 2016 and 2023. Among them, 414 children had received EV-A71 vaccination (376 fully, 38 partially) and 7409 were unvaccinated. Encephalitis, defined by clinical symptoms, neuroimaging evidence, and CSF pleocytosis (>5 WBC/mm
