The impact of smart city construction on urban public health: evaluation using dual machine learning models.
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
Introduction: Global public health is confronted with multiple challenges such as the frequent occurrence of infectious diseases, the increasing burden of chronic diseases, climate change, and the transformation of population structure. These social and environmental factors have exacerbated the complexity and difficulty of public health governance. Digital technologies represented by artificial intelligence and big data are developing rapidly, providing new tools and paradigms for addressing these challenges. Methods: This paper takes the pilot policies of smart cities in China as the standard natural experiment, and uses the panel data of 270 prefecture-level cities in China from 2007 to 2020. It empirically examines the impact of smart city construction (SCC) on public health level (PHL) by adopting a dual machine learning model. Results: The results show that SCC can significantly improve PHL, and the conclusion remains valid after robustness tests such as resetting the machine learning model, instrumental variable method, and multi-dimensional fixation. Mechanism tests show that SCC mainly enhances PHL by improving the quality of the ecological environment, enhancing the level of innovative services, and optimizing the structure of healthy human resources. Heterogeneity analysis revealed that the promoting effect of SCC on PHL was more pronounced in regions such as western China, large cities and key environmental protection cities. Discussion: The research conclusions can not only enrich the theoretical accumulation in the fields of smart cities and public health, but also provide replicable and scalable practical experience for other developing countries to enhance their public health governance capabilities through digital means under resource constraints.
