Assessment of Relative Health Risks of Vibration-Exposed Equipment Operators in Coal Mines.
Article in Indian journal of occupational and environmental medicine. 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
Objective: The present study aims at evaluating the influence of whole-body vibration (WBV) exposure and its contributing factors on musculoskeletal disorders (MSDs) of equipment operators in coal mines. Methodology: In this paper, WBV measurement was conducted for 100 equipment operators exposed to vibration, followed by a questionnaire survey. This questionnaire survey was also extended to 104 workers with limited exposure to vibration. Results: The daily average frequency-weighted acceleration A(8), when compared with health guidance caution zone (HGCZ) of ISO 2631-1, reveals that 15% operators are exposed to likely health risk and 82% to potential health risk. The relative risk of MSDs of vibration-exposed operators was 2.63 times more than the control group. Moreover, when mines were compared, Mine B showed a 3.27 times higher likelihood of vibration hazards compared to Mine A. Conclusion: Equipment operators in mines are exposed to vibration as a part of their occupation. The company management may take preventive measures through design of workplace and work environment for minimizing vibration exposure on operators to reduce MSDs.
