Relationship between Air Pollution and Serum Vitamin D Levels: A Systematic Review and Meta-Analysis.
Article in Advanced biomedical research, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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: Elevated levels of atmospheric pollutants might disrupt the metabolism of vitamin D in the skin. Studies showed inconsistent results about the impact of air pollution on the serum vitamin D level. This study aims to systematically review the influence of air pollution on vitamin D levels. Materials and Methods: The Medline database (PubMed), Web of Science, Scopus, and Google Scholar were systematically searched up to the end of July 2020. All observational, English-language, and human studies that assessed the effect of air pollution on vitamin D levels were included. Results: Among 432 studies, 26 papers were included in the systematic review and five studies in the meta-analysis. Exposure to air pollution was associated with lower vitamin D levels (pooled mean difference (MD) = -8.04, 95% confidence interval (CI): -10.34, -5.75). There was some evidence of heterogeneity between studies (I Conclusion: The findings revealed a reverse correlation between vitamin D levels and air pollution. Air pollutants have an impact on the penetration of solar ultraviolet B (UVB) to the Earth's surface. Consequently, the occurrence of vitamin D deficiency could be linked to air pollution.
