Estimating the epidemic size of chikungunya virus infection in Guangzhou, China, from July to September 2025: a single-center cross-sectional study.
Article in Emerging microbes & infections, 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
Although no previous large-scale outbreak was reported in China in recent years, since July 2025, a surge in the number of chikungunya virus infections has been observed in multiple cities of Guangdong province following the introduction of imported cases, including Guangzhou. Using serological and epidemiological data obtained during a chikungunya outbreak in Guangzhou city, we estimated an attack rate of 22% for chikungunya virus infection. Accounting for case under-reporting is crucial for accurate disease burden assessment and planning of future vaccination programmes.
