Racial disparities in the cause of death among patients with lung cancer in the United States.
Article in Journal of thoracic disease, 2025. 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
Background: Racial disparities in lung cancer have existed in the United States (US) for many years. No studies have been conducted to elucidate the long-term trends of racial disparities in all-cause and cause-specific deaths in lung cancer patients. Our study aimed to explore trends and potential contributing factors of racial disparities. Methods: From the Surveillance, Epidemiology, and End Results (SEER) Program, we obtained the data of lung cancer patients diagnosed between 2000 and 2019, with follow-up until Dec 31, 2020. The cumulative mortality for Black, White, Asian or Pacific Islander (API), and American Indian or Alaska Native (AIAN) was calculated by diagnostic period and cause of death. By using Cox regression models, we determined the relative [hazard ratio (HR)] racial disparities and contributing factors. Results: The incidence and mortality rates during 2000-2019 for lung cancer decreased in all racial groups in men and women, especially for Black men. Despite a downward trend in the cumulative risk of death in racial groups, Black and API patients consistently had the highest and lowest mortality rates from 2000 to 2019, with adjusted HR of 1.14 and 0.83, respectively. The Black-White disparities in all-cause mortality narrowed over time, with adjusted HR of 1.18 [95% confidence interval (CI): 1.15-1.20] during 2000-2004 and 1.14 (95% CI: 1.11-1.16) during 2015-2019. Surgery and liver metastasis had the largest effect on Black-White disparities and API-White disparities, respectively. Conclusions: Our findings reveal persistent racial disparities among lung cancer patients, providing a theoretical basis for interventions to eliminate health disparities.
