Exposure to Polycyclic Aromatic Hydrocarbons, but Not to Dust or Fluorides, in the Norwegian Aluminum Industry Is Associated With Accelerated Annual Decline in Lung Function.
Article in American journal of industrial medicine, 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
purposeThe association between development of chronic airflow limitation and exposures in the aluminum industry is unknown. In a prospective study with nearly 10 years of annual measurements of forced expiratory volume in 1 s (FEV1) and forced vital Capacity (FVC) and concurrent estimates of exposure to dust, total fluorides (TotF) and polycyclic aromatic hydrocarbons (PAH) we investigated the relationship between each of these exposures and annual decline in FEV1 (dFEV1) and FVC (dFVC).
methodsEstimates of exposure to dust, TotF, and PAH were obtained from random samples of 8-h shifts using personal samplers at each of seven Norwegian aluminum plants. A total of 18,332 measurements were used to create a job-exposure matrix. The total number of available spirometries was 20,712 in 3872 workers. Data were analyzed using linear mixed modeling with inverse probability weights for dropouts.
resultsWe found that dFEV1 and dFVC increased during follow-up with linear and quadratic components that were modified by PAH exposure. These linear and quadratic components were estimated at 2.5 mL/year (p = 0.019) and 4.2 mL/year
conclusionWe found a significant effect modification of the relationship between dFEV1 and dFVC, and follow-up time by PAH exposure, indicating that PAH exposure accelerates the annual decline in FEV1 and FVC.
