1 · What the graph read from it

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.

2 · The registry

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

backgroundIschemic heart disease (IHD) continues to be the foremost contributor to global morbidity and mortality. This analysis aims to report an updated assessment of prevalence, deaths, and disability-adjusted life years (DALYs) due to IHD and its attributable risk factors in 204 countries and territories from 1990 to 2021, by age, sex, and socio-demographic index (SDI).

methodsThis analysis used data from the Global Burden of Diseases, Injuries, and Risk Factors Study 2021. IHD was defined as acute myocardial infarction, chronic stable angina, chronic IHD, and heart failure due to IHD. Major indicators used in this study were prevalence, death and DALYs. All estimates were reported as absolute counts and age-standardized rates per 100,000 population, along with their 95% uncertainty intervals (UIs).

resultsGlobally, IHD accounted for 254.3 (95%UI: 221.4 to 295.5) million prevalent cases, 9.0 (95%UI: 8.3 to 9.5) million deaths and 188.4 (95%UI: 177.0 to 198.1) million DALYs in 2021. There was a noticeable decline in the global age-standardized death rate (ASDR) [-31.6% (95%UI: -34.9 to -28.3)] and age-standardized DALYs (ASRDALYs) [-28.8% (95%UI: -32.5 to -25.2)] from 1990 to 2021, with an estimated annual percentage change of -1.3 (95%CI: -1.34 to -1.26) and - 1.2 (95%CI: -1.25 to -1.16), respectively. In 2021, the global prevalence, death, and DALY rates of IHD were higher among males across all age groups, while death and DALY rates reaching a peak in the oldest group for both sexes. Regionally, we found a nonlinear but negative association between age-standardized prevalence rate (ASPR) and SDI. Nationally, similar negative associations were observed between ASRDALYs and SDI. High systolic blood pressure and high low-density lipoprotein cholesterol were the factors contributing most to the deaths and DALYs due to IHD.

conclusionsDespite declining global age-standardized death and DALYs rates of IHD, sustained multilevel prevention strategies remain essential. This requires population-wide risk factor reduction, targeted interventions for high-risk populations, and strengthened community healthcare networks to ensure accessible, guideline-based management.
