Global Burden and Temporal Trends of Brain and Central Nervous System Tumors in Children and Adolescents: A Systematic Analysis for the Global Burden of Disease Study 2021.

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: Central nervous system (CNS) tumors pose major global health challenges. Previous studies often assessed all-age populations without focusing on children and adolescents. We analyzed the burden and temporal trends of CNS tumors among individuals aged < 20 years from 1990 to 2021, with projections to 2036. Methods: Data were obtained from the Global Burden of Disease Study 2021, including annual incidence, mortality, and disability-adjusted life years (DALYs) for brain and CNS tumors. Regions were classified by Socio-demographic Index (SDI) to examine associations between burden and development. Temporal trends were analyzed using the age-period-cohort (APC) model and future projections via the Bayesian APC model. Results: In 2021, an estimated 40,534.53 (95% uncertainty interval [UI]: 33,345.94-49,609.04) new cases of brain and CNS tumors occurred worldwide. The global age-standardized incidence rate (ASIR) was 1.54 (95% UI: 1.27-1.88), and the death rate (ASDR) was 0.76 (0.61-0.93) per 100,000. High-SDI regions showed the highest ASIR and ASDR, while lower-SDI regions faced growing burdens. Mortality and DALYs improved most in Greenland, Serbia, and China. The APC model showed a mild global decline in incidence ( Conclusions: Global CNS tumor burden declined but remains uneven. Enhanced prevention and healthcare access are needed, especially in low-SDI regions.
