Tobacco-Attributable Burden of Early-Onset Ischemic Heart Disease From 1990 to 2023: A Global Analysis Using GBD 2023 and Age-Period-Cohort Modeling.
Article in Clinical cardiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundEarly-onset ischemic heart disease (IHD) is a growing global threat, with tobacco exposure as a key modifiable risk factor. A global assessment of its tobacco-attributable burden is needed.
methodsUsing Global Burden of Disease Study 2023 data, we assessed tobacco-attributable deaths and disability-adjusted life years (DALYs) from early-onset IHD in 204 countries and territories during 1990-2023. Trends were evaluated using estimated and average annual percentage changes (EAPCs and AAPCs). Age-period-cohort (APC) models characterized age, period, and cohort patterns, and Bayesian APC models projected age-standardized rates to 2050. A sensitivity analysis compared the sexes aged 40-54 years.
resultsFrom 1990 to 2023, tobacco-attributable DALYs increased from 15.21 to 17.12 million and deaths from 342 900 to 386 300. Conversely, ASDR declined from 381.54 to 221.82 per 100 000 (EAPC -1.84%, 95% CI -1.94 to -1.73) and ASMR from 8.69 to 4.96 per 100 000 (EAPC -1.88%, 95% CI -1.98 to -1.77). Male rates remained higher, including when both sexes were restricted to ages 40-54 years. APC analyses showed significant favorable net drifts and lower period and cohort rate ratios in recent periods and birth cohorts. Bayesian projections suggested declining ASDRs through 2050, whereas ASMR estimates were stable or slightly increased with widening uncertainty.
conclusionThe age-standardized burden of tobacco-attributable early-onset IHD declined substantially between 1990 and 2023, but absolute DALYs and deaths increased and disparities by development level and sex persisted. Stronger tobacco control and integrated cardiovascular prevention are needed, particularly for high-risk males and in low- and middle-SDI settings.
