Tobacco-driven digestive disease burden: A China-US comparative analysis, 1990-2035.
Article in Tobacco induced diseases, 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
Introduction: Smoking is a well-established risk factor for digestive diseases, yet direct comparisons of smoking-attributable digestive disease burden between nations with divergent tobacco control trajectories remain scarce. This study compared temporal trends, driving factors, and future projections of this burden in China and the United States from 1990 to 2023. Methods: Using Global Burden of Disease 2023 data, we analyzed smoking-attributable digestive disease deaths and disability-adjusted life years. Joinpoint regression assessed temporal trends. Decomposition analysis partitioned burden changes into population growth, aging, and epidemiological components. Bayesian age-period-cohort models projected burden to 2035. Results: From 1990 to 2023, age-standardized mortality rates for smoking-attributable digestive diseases declined by 77.2% in China (average annual percentage change, AAPC= -4.32; 95% CI: -4.42 - -4.21; p<0.001) and 58.0% in the United States (AAPC= -2.57; 95% CI: -2.66 - -2.48; p<0.001). Despite these rate reductions, absolute smoking-attributable deaths among those aged 90-94 years increased by 663.6% in China and 131.5% in the United States. Epidemiological change was the dominant driver of burden reduction, contributing 374.4% and 349.8% of the overall smoking-attributable death reduction in China and the United States, respectively, outweighing combined demographic pressures. Joinpoint analysis identified a transient increase in US smoking-attributable death rates during 2018-2021 (APC=2.51; p<0.05). Projections indicated continued declines in smoking-attributable rates through 2035. Conclusions: Despite substantial epidemiological improvements, population aging increasingly offsets rate declines, particularly among the oldest adults. Sustained, age-targeted tobacco control strategies are essential to address the evolving demographic burden.
