Long-term exposure to ambient air pollution and risk of incident acute myocardial infarction in a nationwide register-based cohort study.
Article in International archives of occupational and environmental health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
objectiveThe aim of this study was to investigate the association between long-term exposure to ambient air pollution at the residential address and the risk of acute myocardial infarction (AMI) in a younger working population.
methodsThe study population included all Danish residents aged 35–50 in 1995 with employment and no previous diagnosis of AMI. Information on AMI was obtained through national registries. We estimated the exposure to fine particulate matter (PM2.5), nitrogen dioxide (NO2), elemental carbon (EC) and primary organic aerosols (POA) from 1979 onwards based on the Danish integrated multi-scale air pollution modeling system. Poisson regression models were used to estimate incidence rate ratios (IRR) with 95% confidence intervals (CI) of AMI.
results903,415 individuals were included in this cohort, covering almost 20 million person-years of follow-up between 1996 and 2018. In total 35,511 developed AMI. Our main analyses showed a clear exposure-response relationship between cumulative exposure to each of the air pollutants and incident AMI. Exposure was categorized into quartiles (Q1–Q4), with Q1 as reference. The most pronounced association was observed for PM2.5 with IRRs of 1.08 [95% CI 1.04,1.13], 1.14 [95% CI 1.09,1.20] and 1.24 [95% CI 1.18,1.31] in Q2–Q4 in model 4 (fully adjusted). The associations were observed for both sexes and across age groups.
conclusionOur findings suggest that long-term exposure to PM2.5, NO2, EC, and POA are associated with an increased risk of incident AMI, also pertaining to the younger population (< 55 years).
