Adverse occupational outcome among workers with occupational asthma: A systematic review and meta-analysis of influencing factors.
Synthesis in Scandinavian journal of work, environment & 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
objectivesOccupational asthma (OA) often interferes with workers' ability to maintain employment. We synthesized the prevalence of adverse occupational outcome (AOO)-unemployment, chronic sick leave, disability, and early retirement-caused by OA.
methodsFollowing PRISMA methodological recommendations and PROSPERO registration (CRD42024528750), we searched PubMed, Scopus, and Web of Science for studies published between January 1980 and September 2024 that reported quantitative employment outcomes in adults with OA. Risk of bias was assessed using the Joanna Briggs Institute Checklist for Prevalence Studies. Pooled prevalences were calculated using random-effects generalized linear mixed models on the logit scale with Hartung-Knapp 95% confidence and prediction intervals (CI and PI).
resultsA total of 25 studies comprising 3393 participants were included. The pooled prevalence of AOO was 35.9% (95% CI 28.6-43.9; I
conclusionsMore than one-third of workers with OA experience an AOO. The findings highlight the need for harmonized outcome definitions and for interventions integrating early referral, exposure control, and structured return-to-work programs to avoid AOO.
