Temporal changes in occupational risks of COVID-19 hospitalisation in Germany, 2020-2021: a case-cohort study.
Article in BMJ 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
Background: During the COVID-19 pandemic, certain occupational groups faced elevated infection risks. This study investigated changes in occupational risks of COVID-19 hospitalisation between 2020 and 2021. Methods: Using a case-cohort design, we analysed data from Germany's Allgemeine Ortskrankenkasse statutory health insurance, including 28 925 COVID-19 hospitalisation cases and 498 484 non-cases in 2021. HRs with administrative workers as reference were calculated using weighted and stratified Cox regression models, adjusting for age, sex, comorbidities and socioeconomic status. The ratio of relative risk (RRR) assessed the differences between years. Results: Healthcare workers showed the greatest reduction in relative risk (HR Conclusions: We observed a risk reduction in some sectors, particularly healthcare, likely due to vaccination and protective measures. However, certain occupations maintained elevated risks, perhaps due to unavoidable close physical contact. These findings suggest the need for sector-specific approaches to occupational health protection and permanent structural changes in workplace organisation for future pandemic preparedness.
