Lifetime risk of respiratory system cancers across 185 countries: Global variation, socioeconomic inequalities, and ecological associations with air pollution.
Article in Preventive medicine reports, 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
Objective: To estimate the lifetime risks of developing and dying from respiratory system cancers across 185 countries and territories and to examine their associations with socioeconomic development and air pollution. Methods: GLOBOCAN 2022 data for 185 countries and territories were combined with United Nations life tables to estimate lifetime risks using an adjusted-for-multiple-primaries framework. Country-level air pollution indicators for 2022 were obtained from OpenWeather. Estimates were stratified by Human Development Index (HDI) and World Bank income groups, and associations between lifetime risk and PM2.5, PM10, NO2, and SO2 were assessed using univariable linear regression. Results: Globally, the lifetime risk of developing and dying from lung cancer was 4.92% and 4.08%, respectively, far exceeding those for laryngeal cancer (0.33% and 0.20%). A marked socioeconomic gradient was identified: lung cancer incidence risk ranged from 0.34% in low-HDI countries to 5.45% in very high-HDI countries. All four pollutants were positively associated with lifetime risk, with PM2.5 showing the strongest correlation in the primary univariable analyses. Conclusions: Substantial geographic and socioeconomic disparities exist in respiratory cancer lifetime risk, with lung cancer as the dominant driver. The observed ecological associations with air pollutants support further investigation of environmental factors in cancer prevention.
