Global burden and cross-country inequalities of alcoholic cardiomyopathy: A 1990-2021 analysis.

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
Introduction: Alcoholic cardiomyopathy (ACM) remains a significant yet understudied contributor to global cardiovascular disease, with substantial socioeconomic influences on its epidemiology. This study investigates the global burden, temporal trends, and health inequalities of ACM across 204 countries. Methods: Utilizing the Global Burden of Disease 2021 data (1990-2021), we analyzed age-standardised mortality (ASMR), prevalence (ASPR), and disability-adjusted life years (ASDR) for populations aged ≥15 years. A trend analysis employed the estimated annual percentage change (EAPC), while inequality metrics (Slope Index of Inequality, Concentration Index) assessed socioeconomic disparities using the socio-demographic index (SDI). Results: Globally, ACM caused 47,073 deaths and 2.19 million DALYs in 2021, with an overall decreasing trend (ASMR EAPC: -1.72 %). High-middle SDI regions bore the highest burden (ASDR: 88.27/100,000), particularly Eastern Europe (ASDR: 510.47). We identified a distinct nonlinear relationship with SDI: burden peaked at SDI≈0.75 (p < 0.001), with Eastern Europe showing the steepest rise/decline. Inequality analysis revealed persistent concentration in high-SDI regions (positive concentration indices: 0.51-0.60), though relative inequalities decreased over time. Kazakhstan exhibited the most rapid burden increase (ASMR EAPC: +11.15 %), while Southern Latin America showed maximal decline (ASMR EAPC: -6.69 %). Conclusions: ACM disparities are strongly linked to socioeconomic development, highlighting the need for targeted alcohol policies in high-burden regions and equitable healthcare resource allocation.
