The impact of winter clean heating in northern China on air quality and its spatial spillover effect of the pilot cities.
Article in Scientific reports, 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
Air pollution is a serious environmental problem China has faced in recent years, with winter coal combustion being one of the main sources of air pollution in the northern region. Based on meteorological and economic statistical data from 285 Chinese cities, this study uses the spatial Durbin Difference-in-Difference model to evaluate the actual effect on air quality of the winter clean heating pilot implemented in the northern region since 2017. Our research found that: (1) Pilot policy significantly reduced the level of pollutants in cities, and the air quality index (AQI) score decreased by 3.798. Six air pollutants that make up AQI, including PM
