Association between air pollution and emergency department visits for unintentional injuries in four cities of Shandong Province, China.

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
Objective: To study the relationship between emergency department visits for unintentional injuries and air pollutants in four cities in Shandong Province, China (2019-2022). Methods: From 2019 to 2022, the data on air pollutants and unintentional injury emergency department visits were extracted from four cities in Shandong Province (Dezhou, Jinan, Zibo, and Heze). We used the dynamic factor model (DFM) to determine the trend of emergency visits and the distributed lag nonlinear model (DLNM) to analyze the lag effect of air pollutants on these visits. We also conducted a meta-analysis to summarize the impact estimates of air pollutants on emergency visits. Results: The dynamic factor model showed that from 2019 to 2022, the number of emergency visits for unintentional injuries in the four cities in Shandong Province was cyclical, with the highest number of emergency visits in summer every year. PM Conclusion: Emergency visits for unintentional injuries in the four cities exhibited an annual cyclical pattern, with the peak occurring in summer. Exposure to high concentrations of air pollutants increased the risk of unintentional injuries, with distinct effects observed across different pollutants, each exhibiting specific single-day and cumulative lag effects.
