Exposure to household air pollution in relation to stomach and esophageal cancer in Xuanwei, China.
Article in Environment international, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Household air pollution (HAP) is a global health burden affecting about half of the world's population. In Xuanwei, China, individuals experience high concentrations of various HAP constituents, particularly polycyclic aromatic hydrocarbons (PAHs). Here, the association between HAP constituents and cause-specific mortality from stomach and esophageal cancer was investigated. The study was conducted in a cohort of 42,420 subjects from Xuanwei, China. Participants were followed from 1976 to 2011. Type of fuel used was collected through a questionnaire and categorized into lifetime smoky vs. other fuel use. Annual exposures were predicted for 43 HAP constituents and 5 clusters were identified using hierarchical clustering. Cox regression was used to estimate the association between lifetime smoky coal use and pollutant clusters with stomach (n = 143) and esophageal (n = 39) cancer. All models were stratified by sex and birth cohort and adjusted for smoking status and education. Lifetime smoky coal use (hazard ratio [HR] = 1.40, 95 % confidence interval [CI]: 1.00, 1.96) and a large PAH cluster, PAH37 (HR = 1.59, 95 % CI: 1.19, 2.13 per standard deviation [SD]), were associated with stomach cancer mortality. Similarly, lifetime smoky coal use (HR = 2.84, 95 % CI:1.38, 5.85) and PAH37 (HR = 1.75, 95 % CI: 1.01, 3.04 per SD) were associated with esophageal cancer mortality. Stratified analyses found that the association between PAH37 and stomach cancer was higher among women compared to men (P-interaction = 0.02). This study identified an association between HAP and risk of stomach and esophageal cancer mortality in a highly exposed population. Future work is needed to investigate potential risk differences by timing of exposure.
