The Evolving Burden of Age-Related Macular Degeneration in China (1990-2023): Insights from an Aging Society and the Anti-VEGF Era.
Article in Clinical epidemiology, 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: Age-related macular degeneration (AMD) is a leading cause of vision loss in the elderly. China bears the world's largest AMD burden. This study analyzes the evolving AMD burden in China (1990-2023) and the impact of anti-VEGF therapy. Methods: We analyzed data from the Global Burden of Disease (GBD) 2023 study using joinpoint regression, decomposition analysis, and Bayesian modeling. A supplementary meta-analysis of single-arm studies was conducted to assess anti-VEGF efficacy in Chinese patients. Results: From 1990 to 2023, China's age-standardized prevalence rate (ASPR) and disability-adjusted life year rate (ASDR) for AMD decreased by -0.67% and -1.48% annually, respectively. In 2023, China accounted for 35.82% of global cases and 30.25% of global DALYs. A supplementary meta-analysis of 13 single-arm observational studies showed a pooled efficacy rate of 74% for anti-VEGF drugs in China, albeit with substantial heterogeneity (I Conclusion: Despite a declining age-standardized burden, China's absolute AMD burden remains substantial due to rapid population aging and other challenges. The temporal association between anti-VEGF therapy availability and the accelerated burden decline suggests a potential contribution of this treatment, though causality cannot be directly inferred from this ecological analysis. The observed trends likely reflect multiple factors, including improved healthcare access, early diagnosis, socioeconomic development, and anti-VEGF therapy. Comprehensive strategies focusing on prevention and equitable healthcare access are needed.
