The nonlinear impact of air pollutants and solar radiation exposure on the risk of hospitalisation for pterygium among adults in Shanghai, China: a time series analysis.
Article in Journal of global health, 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
Background: In recent years, many studies have focused on the effects of air pollution on ocular surface health. However, there is currently little research on the relationship between pterygium and air pollution. We aimed to investigate the effects of air pollutants and solar radiation on the progression of pterygium in adults through a 5-year time series analysis. Methods: After collecting the meteorological data and clinical visits for pterygium in Shanghai, China from 2017 to 2023, we established a distributed lag nonlinear model (DLNM) for statistical analysis. We also conducted subgroup analysis according to age and sex to investigate the impact of risk factors on different populations. Results: This cohort included a total of 57 211 cases. We found that solar radiation, particulate matter less than 2.5 micrometre (μm) (PM Conclusions: Our results suggested that in addition to solar radiation, which is recognized as a risk factor for pterygium, PM
