Burden and Trends of Aortic Aneurysms in Individuals Aged 55 and Older from 1990 to 2021: A Systematic Analysis of the Global Burden of Disease Study 2021.
Article in Global heart, 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
Background: This study aims to assess the burden of aortic aneurysm (AA) among individuals aged 55 years and older from 1990 to 2021 at global, regional, and national levels. Methods: Data from the Global Burden of Disease (GBD) 2021 were analyzed to estimate disability-adjusted life years (DALYs), deaths, age-standardized DALYs rates (ASDR), age-standardized mortality rates (ASMR), and average annual percentage change (AAPC) associated with AA. We employed Joinpoint regression to characterize temporal trends in the AA burden, decomposition analysis to quantify the contributions of key drivers, the Slope Index of Inequality (SII) and Concentration Index of Inequality (CII) to assess health disparities, frontier analysis to benchmark development-stratified achievable disease control levels, and a Bayesian Age-Period-Cohort (BAPC) model to project AA burden trajectories through 2050. Results: Between 1990 and 2021, global deaths and DALYs due to AA among individuals aged 55 years and older increased by 73.92% and 62.57%, respectively. In contrast, ASMR and ASDR exhibited a declining trend, with AAPC values of -1.07 and -1.12, respectively. Population growth showed strong correlations with increased deaths and DALYs. SII and CII decreases indicated diminished transnational disparities in AA burden. Projections for 2050 indicate a continued rise in deaths and DALYs, while ASMR and ASDR are expected to decline further. Conclusions: Although global ASMR and ASDR for AA declined from 1990 to 2021, the absolute number of deaths and DALYs increased, with notable regional variations in disease burden. Targeted public health interventions and optimized resource allocation are essential to mitigate the burden of AA.
