Global and regional burden of four drug use disorders in the elderly, 1990 to 2021: an analysis of the global burden of disease study.
Article in BMC geriatrics, 2025. 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
backgroundAs the global population ages, the burden of drug use disorders (DUDs) among the elderly is rising. It is imperative to conduct a quantitative analysis of the disease burden affecting this vulnerable population.
methodsUtilize the Global Burden of Disease Study 2021 database to obtain incidence rates and disability-adjusted life years (DALYs) for opioids, cocaine, amphetamines, and cannabis among the elderly (aged 60-89) across 204 countries and 5 SDI regions from 1990 to 2021. Employ Joinpoint regression analysis to calculate the average annual percentage change (AAPC) of age-standardized incidence rates (ASIR) and age-standardized DALYs rates (ASDR). Use the Das Gupta method to decompose and analyze the impacts of changes in age structure, population growth, and epidemiology on DALYs during this period. Finally, apply the Nordpred model to predict DALYs for global and high-burden regions from 2022 to 2035.
resultsOf the four DUDs, opioids have the highest disease burden. Joinpoint analysis indicates that from 1990 to 2021, the ASIR and ASDR remained stable. Cocaine use disorder ASIR remained stable, but ASDR increased with an AAPC of 0.94 (95% CI 0.77-1.11). The burden of amphetamine and cannabis use disorders generally stabilized. Geographic heterogeneity was evident at regional and national levels, with ASDR for all four DUDs increasing in high-SDI areas while remaining stable or declining in other SDI areas. High-income North America, represented by the United States, shows a higher burden of disease. Decomposition analysis shows that population growth is the main factor affecting the change in the burden of DUDs in most regions, and high-income North America is mainly affected by epidemiological changes. According to the Predictive models, the DALYs of DUDs in the global elderly population is still on the rise, especially in the man group in North America.
conclusionThe burden of DUDs among the elderly varies across countries, regions, SDI levels, and genders, underscoring the need for targeted public health policy adjustments and strategic allocation of medical resources to mitigate this burden.
