Integrated study for the impacts of air pollution and climate conditions on road traffic accidents.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Traffic accidents are among the most frequent incidents in society, directly posing threats to human life and property loss. In 2022, China recorded 256,409 traffic accidents, resulting in direct property losses of 1.2393 billion yuan. Analyzing potential factors affecting road traffic safety is crucial to reduce accidents and subsequent losses. This article focuses on traffic accidents, climate, and air pollution in Chengdu, a megacity in southwestern China. Linear and nonlinear models are used to analyze the impacts of air pollution and climate conditions on road traffic accidents. The linear model examines the linear relationships between the response variable (number of traffic accidents) and various indices initially. After verifying nonlinear dependencies using a novel statistical test, XGBoost and generalized additive models are further utilized to capture the nonlinear relationship between response and covariate. The results indicate that climate indices, such as temperature and precipitation, have varying impacts within different ranges of covariate. Integrating linear and nonlinear models can enhance the interpretation ability of statistical analysis.
