Long-term exposure to air pollution and lung cancer incidence: findings from improved exposure assessment and extended population.
Article in Cancer causes & control : CCC, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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
purposeAccumulating evidence suggested long-term exposure to air pollution as a risk factor of lung cancer. Recent efforts confirmed the association based on extended population and individual exposure by leveraging administrative databases and complete address information. However, few studies achieved simultaneous improvements. Using the 2 million cohort along with their individual residential exposures, this study aimed to investigate the association of four criteria pollutants and incident lung cancer in the Seoul Metropolitan Area, South Korea.
methodsOur study population included 2,035,278 people aged ≥ 30 years and without cancer for 2002-2006 from the National Health Insurance System database. We identified lung cancer incidence for 2007-2016 and assessed individual long-term exposure to particulate matter ≤ 10 µm and 2.5 µm in diameter (PM
resultsThere were 18,229 lung cancer new cases over 10 years. We did not find the association for all four pollutants (PM
conclusionOur findings of no association contradictory to existing evidence, despite the considerable improvement in exposure assessment and population size, suggest further examination by integrating histological variation and indoor and/or personal exposure.
