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: Headache disorders significantly impact health and functioning, yet studies on their global burden across all age groups are limited. This study utilizes data from the Global Burden of Disease (GBD) 2021 to investigate the global burden of headache disorders. Methods: This analysis draws on GBD 2021 data, covering 204 countries and territories. We investigated the prevalence, incidence, and DALYs for headache disorders from 1990 to 2021, calculating Estimated Annual Percentage Change (EAPC) to analyze temporal trends. Additionally, decomposition analysis was used to evaluate the contributions of aging, population growth, and epidemiological changes. The slope index of inequality and concentration index were employed to assess inequalities in disease burden. Results: From 1990 to 2021, the global prevalence of headache disorders increased significantly, reaching approximately 2.81 billion cases in 2021, a 57.16% increase from approximately 1.79 billion cases in 1990. During this period, the global Age-Standardized Prevalence Rate (ASPR) and Age-Standardized DALY Rate (ASDR) both showed gradual increases, while the Age-Standardized Incidence Rate (ASIR) remained stable, with EAPC values of 0.01, 0.04 and-0.0002, respectively. High Socio-demographic Index (SDI) regions exhibited the highest rates of ASPR, ASIR, and ASDR, whereas Middle SDI regions experienced the fastest growth, with EAPC values of 0.17, 0.17, and 0.18, respectively. The SDI exhibited significant positive correlations with the EAPC of ASPR ( Conclusion: Headache disorders continue to impose a growing burden globally, with marked regional and socio-economic disparities. Addressing these trends requires targeted public health interventions, particularly in high-burden and low-resource settings.
