Sarcopenia, Eosinophil-to-Platelet Ratio, and C-Reactive Protein as Predictors of Adverse Occupational Health Outcomes in Workers with Chronic Obstructive Pulmonary Disease: A Prospective Cohort Study.
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
Background: Chronic obstructive pulmonary disease (COPD) affects many industrial workers and can lead to absenteeism, disability, and other adverse occupational outcomes. Identifying biomarkers that predict poorer work-related prognosis in COPD could help target workplace accommodations and interventions. This study evaluated whether sarcopenia, eosinophil-to-platelet ratio (EPR), and C-reactive protein (CRP) levels predicted adverse occupational health outcomes, such as missed workdays, job loss, and work disability in workers with COPD exacerbations. Methods: This prospective cohort study enrolled 200 working-age adults (18-65 years) with COPD who were employed at the time of an acute exacerbation requiring hospitalization. Sarcopenia, EPR, CRP, and other clinical characteristics were assessed at baseline. Participants were followed for 12 months to ascertain adverse occupational outcomes, including absenteeism (>14 days of missed work), employment termination, and application for disability benefits. Regression analysis determined biomarker associations with occupational outcomes. Results: Over 12 months, 22% of participants experienced prolonged absenteeism, 11% lost employment, and 9% applied for disability. After adjustment, low EPR (OR 2.81, 95% CI 1.23-6.41) and high CRP (OR 2.67, 95% CI 1.19-5.99) were associated with absenteeism. Only EPR (OR 3.25, 95% CI 1.07-9.88) predicted employment loss. Both low EPR (OR 4.12, 95% CI 1.41-11.98) and high CRP (OR 2.93, 95% CI 1.02-8.38) increased the odds of disability application. Sarcopenia was not significantly associated with the occupational outcomes after controlling for covariates. Conclusion: Among working adults with COPD, low EPR and high CRP levels were robust predictors of prolonged absenteeism, job termination, and disability application following exacerbations. Assessing these inflammatory biomarkers could identify workers at elevated risk of poor occupational trajectories who may benefit from targeted workplace accommodations, rehabilitation programs, or other interventions to preserve employment.
