Occupational risk of COVID-19 related hospital admission in Skåne, Sweden: A register-based cohort study.
Article in PloS one, 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
purposeGiven the paucity of data regarding workplace risk of COVID-19, particularly from countries with limited lockdowns, we aimed to quantify the occupational risks of COVID-19-related hospital admission among workers in Sweden.
methodsWe identified 607,179 employed individuals, 20-69 years of age, in Skåne, Sweden. From December 31st, 2019-December 31st 2021, 2,633 incident COVID-19-related admissions were identified. Using a job exposure matrix for risk of becoming infected with the SARS-CoV-2 virus in an occupational setting we delineated occupations with low work-related risk. Based on these reference occupations, incidence rate ratios (IRR) and 95% confidence intervals (CI) were computed by Poisson regression for four-digit occupations defined by the International Standard Classification of Occupations job codes (ISCO-08).
resultsAfter adjusting for various sociodemographic characteristics, risk compared to reference occupations was elevated among healthcare occupations as a group (IRR 1.31; 95% CI: 1.13-1.51), with nurses, healthcare assistants, and nursing aids having the highest IRRs (ranging from 1.28-1.54). In the educational sector, no apparent elevated overall risk was observed (IRR 1.03; 95% CI: 0.86-1.23). For the transportation sector, an overall excess risk was observed (IRR 1.34; 95% CI: 1.10-1.65), with bus and tram drivers having the highest risks. IRRs < 1 were observed among electricians, some builders, and software developers.
conclusionExcess risk of COVID-19-related hospital admission was observed in many patient-facing occupations across the healthcare sector and in multiple occupations within the transportation sector. However, despite limited lockdowns and legislation, no apparent increased risks were observed in the educational or retail sales sectors.
