Work-Related Exposures Mediate Occupational Class Disparities in SARS-CoV-2 Infection in France.
Article in International journal of public health, 2026. 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
Objectives: This study examines SARS-CoV-2 infection by occupational class (OC) among working adults during the early pandemic in France and the mediating role of work-related exposures in regions highly and less affected by COVID-19. Methods: We analyzed data from 46,849 workers in the French EpiCoV cohort. SARS-CoV-2 infection was defined by self-reported COVID-19-like symptoms between mid-March and the end of June 2020. We related OC with reporting COVID-19-like symptoms in both regions and assessed the mediating effect of work-related exposures using the Karlson-Holm-Breen method of mediation analysis. Results: During the study period, 7.1% of workers reported COVID-19-like symptoms. In less-affected regions, the highest OC workers reported symptoms more often than the lowest, while in the highly affected regions, middle OCs reported symptoms more often than those in the upper class. Regardless, work-related factors increased symptom risk in the middle and lower OCs compared to the highest OC. Conclusion: Distinct transmission dynamics shaped the evolution of occupational class disparities during the early pandemic. Workplace exposures played a significant role in these disparities, even when offset by other exposure-related factors.
