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
introductionIschemic heart disease (IHD) remains a leading global health challenge, with smoking identified as a key modifiable risk factor. China, with its high smoking prevalence and aging population, faces a growing burden of smoking-related IHD. This study evaluates the disease burden of smoking-related IHD in China from 1990 to 2021 and projects future trends to inform targeted interventions.
methodsUsing data from the Global Burden of Disease (GBD) 2021 (1990-2021) and the cross-sectional baseline survey of the China Health and Retirement Longitudinal Study (CHARLS, Wave 1, 2011-2012), we analyzed trends in mortality, disability-adjusted life years (DALYs), years lived with disability (YLDs), and years of life lost (YLLs). Joinpoint regression identified temporal trends, and an autoregressive integrated moving average (ARIMA) model forecast disease burden up to 2036. The CHARLS analysis included participants aged ≥45 years with complete smoking and health records. Multivariable logistic regression assessed the association between smoking status and heart disease likelihood in CHARLS participants.
resultsCHARLS data revealed that former smokers had an 84% higher likelihood of heart disease than never smokers (adjusted odds ratio, AOR=1.84; 95% CI: 1.50-2.25). GBD analysis showed that China's age-standardized mortality rate (ASMR) for smoking-related IHD surpassed global and US levels after 2005, with males bearing a significantly higher burden than females. Joinpoint regression identified key turning points, with male ASMR rising until 2010 before declining slightly, while female indicators consistently improved. ARIMA projections suggest male ASMR will remain high (39.01; 95% UI: 22.69-55.33) by 2036, indicating persistent challenges.
conclusionsThe burden of smoking-related IHD in China exceeds the global average and reveals significant gender disparities, with a worsening burden for males and improvement for females. There is a critical need for more effective smoking control measures aimed at the male population to tackle this major public health issue.
