Characteristics and occupational exposure assessment of VOCs in different coal mines.
Article in Frontiers in public 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
Introduction: The occupational health risk to miners from exposure to volatile organic compounds (VOCs) in underground coal mines has not been adequately quantified. This study aimed to investigate the pollution characteristics and assess the health risks of VOCs in three typical mining areas. Methods: VOC concentrations and compositions were monitored and analyzed across different locations (working face, air return tunnel, air intake tunnel) in three distinct mines: Pan San Mine, Qinghai Yuqa Mine, and Hongliulin Mine, which employed different mining and transport methods. Results: The main findings were: ① Underground VOC concentrations substantially exceeded surface levels, with peaks of 10.8 mg/m Discussion/Conclusion: The analysis revealed that for the limited subset of VOCs with established occupational exposure limit values (17 of 116), exposure indices were significantly below 1. Furthermore, exposure to the remaining compounds was also negligible. These results indicate that, under the studied conditions, the observed VOC levels did not pose a significant occupational health risk.
