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
Aim: To describe nationally representative trends in overall and product-specific tobacco use, including cigarettes, heated tobacco products (HTPs), and electronic cigarettes (e-cigarettes), in Japan from 2017 to 2025. Methods: Data came from repeated cross-sectional nationwide surveys of the Japanese population using stratified two-stage random sampling. Self-administered questionnaires assessed tobacco use. Past-30-day prevalence of overall, product-specific, and multiple-product use was estimated using survey-weighted logistic regression, with marginal predicted prevalence standardized to the 2025 age-sex structure. Results: Among 16,499 participants, overall past-30-day tobacco use declined from 24.3% (95% confidence interval [CI]: 22.6-26.0%) in 2017 to 21.0% (CI: 19.4-22.7%) in 2025. Cigarette use decreased from 20.7% (CI: 19.0-22.3%) to 12.3% (CI: 11.1-13.6%), whereas HTP use increased from 5.3% (CI: 4.4-6.1%) to 11.7% (CI: 10.3-13.0%). e-cigarette use remained low, ranging from 0.7% to 1.3%. The most common multiple-product pattern was concurrent cigarette and HTP use, increasing from 2.5% (CI: 1.9-3.1%) to 4.1% (CI: 3.3-4.9%). Conclusion: Overall tobacco use in Japan declined modestly during 2017-2025, alongside a marked decrease in cigarette use and an increase in HTP use, while e-cigarette use remained limited. These findings suggest a shift in tobacco use, with increased HTP use partially offsetting reductions in cigarette smoking.
