Short-term exposure to CO and NO
Article in Frontiers in public health, 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
Background: Short-term exposure to ambient air pollution has been associated with Kawasaki disease (KD), however, evidence from cold climates remains limited. We aim to evaluate the association between short-term ambient pollutant exposure and KD onset in a cold region of China. Methods: We conducted an ecological time-series study based on aggregated daily counts of hospital-diagnosed KD onset cases. Individual clinical records from 2,562 hospitalized patients diagnosed with KD at two large tertiary medical centers between January 1, 2015, and December 31, 2022, were used to identify eligible cases and determine the dates of first fever onset. Our analysis included a year-round evaluation of multiple ambient pollutants pertinent to both heating and non-heating periods typical of cold regions. We assessed six pollutants (PM Results: High CO concentration (RR = 1.172; 95% CI: 1.024-1.340) and high NO₂ concentration (RR = 1.117; 95% CI: 1.009-1.237) were associated with elevated KD risk at lag 0 under single-day lag analysis. Significant cumulative effects were observed for CO (lag 0-6: RR 1.838; 95% CI: 1.022-3.306) and NO Conclusion: Short-term exposure to CO and NO₂ was associated with increased daily hospital-diagnosed KD onset cases.
