Air Pollution Control and Residents' Weight: Empirical Evidence From China's Action Plan.
Article in Health economics, 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
Air pollution is a significant environmental issue with widespread impacts on public health. Evidence on the causal effect of air pollution control policies on weight-related outcomes remains limited. This study fills this gap by leveraging the Air Pollution Prevention and Control Action Plan as a quasi-natural experiment, combining four waves (2010, 2012, 2014, 2016) of panel data from the China Family Panel Studies (CFPS). Employing a difference-in-differences framework, we find that implementing this policy significantly reduces overweight risk among residents. Mechanism analyses indicate that the policy primarily lowers overweight risk by increasing physical exercise frequency and alleviating depressive symptoms. Further heterogeneity analyses show this impact is particularly pronounced among urban residents, young adults, females, and individuals with lower educational attainment. Our findings clarify the causal link between environmental regulation and population health, and provide actionable insights for policymakers to design coordinated interventions that leverage air quality improvements to advance public health goals.
