Association between short-term exposure to ambient ozone concentration and influenza incidence in Kawasaki City, Japan: a time-stratified case-crossover analysis.
Article in BMC public health, 2025. 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
backgroundSeasonal influenza continues to pose a significant global public health challenge owing to its considerable disease burden, making it imperative to elucidate its potential driving factors. Although the roles of meteorological factors such as temperature and absolute humidity have been extensively investigated, research quantifying the burden of ambient ozone (O₃) as an environmental determinant of influenza, particularly among vulnerable populations, remains limited. The aims of this study were to assess short-term effects of photochemical oxidants (O
