Burden of disease in anxiety disorders: trends, projections and relationship to human resources for health.
Article in Discover mental health, 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
backgroundAnxiety disorders are among the most prevalent mental disorders worldwide and impose a substantial burden on public health systems. This study aimed to comprehensively assess the global burden of anxiety disorders, examine long-term temporal trends, explore their associations with human resources for health (HRH), and project future disease burden.
methodsData were obtained from the Global Burden of Disease (GBD) 2021 study. We first described the global burden of anxiety disorders in 2021 and its geographical distribution across countries and regions. We then analyzed temporal trends in incidence, prevalence, and disability-adjusted life years (DALYs) from 1990 to 2021. In addition, correlations between anxiety disorder burden and HRH were assessed. Finally, future trends from 2022 to 2050 were projected using multiple statistical models.
resultsIn 2021, anxiety disorders accounted for 53.91 million incident cases worldwide, with an age-standardized incidence rate of 678.25 per 100,000 population. The global number of prevalent cases reached 359.21 million, and the total number of DALYs was 42.51 million. China had the highest absolute number of cases, whereas Portugal had the highest age-standardized prevalence rate. Correlation analyses showed moderate associations between several HRH categories and the burden of anxiety disorders; traditional and complementary medicine practitioners were weakly negatively correlated with DALYs. Model-based projections suggest that the global burden of anxiety disorders may continue to increase over the next 25 years.
conclusionAnxiety disorders remain a major global public health challenge. These findings provide updated evidence on their epidemiological burden and may help inform health resource allocation and long-term mental health planning.
