Extreme Cold Events and Pediatric Asthma Outpatient Visits: The Modifying Role of Ambient Carbon Monoxide and Sulfur Dioxide.
Article in Journal of asthma and allergy, 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
Purpose: Extreme cold exposure may trigger respiratory morbidity in children, but whether concurrent ambient air pollution modifies cold-related risks of pediatric asthma remains unclear. This study evaluated associations between extreme cold events and pediatric asthma outpatient visits and assessed whether these associations differed according to ambient pollutant concentrations. Patients and methods: We conducted a time-series study of 62,167 pediatric asthma outpatient visits among children diagnosed with asthma at a tertiary children's hospital in Nanjing, China, from 2019 to 2024. Daily asthma visits were linked with meteorological variables and ambient concentrations of PM Results: Overall, extreme cold events were not significantly associated with pediatric asthma outpatient visits. However, stronger associations were observed during periods with higher CO and SO Conclusion: The association between extreme cold events and pediatric asthma outpatient visits may depend on concurrent gaseous pollutant conditions. Relatively elevated CO and SO
