A cross-sectional analysis of the global burden of childhood leukemia from 1990 to 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
backgroundChildhood leukemia is a common malignant tumor worldwide, affecting survival rates and posing medical and public health challenges. Assessing its global burden is essential for informing prevention, treatment, and policy efforts.
methodsThis is a cross-sectional study based on data from the 2021 Global Burden of Disease (GBD) study, covering the years 1990 to 2021 and including 204 countries and regions. We analyzed the incidence, mortality, disability-adjusted life years (DALYs), and estimated annual percentage changes (EAPCs) for childhood leukemia. Subgroup analyses were conducted by age, gender, region, and Socio-Demographic Index (SDI) levels to explore disparities and trends.
resultsSince 1990, the global burden of childhood leukemia has decreased significantly, with a 59.03% reduction in DALYs. Chronic myeloid leukemia (CML) experienced the largest decline, with incidence, mortality, and DALYs reduced by more than 70%. However, disparities persist: boys generally have a higher burden, and acute lymphoblastic leukemia (ALL) remains the most common subtype. East Asia and Andean Latin America reported the highest burden of ALL in 2021. Incidence is highest in high-SDI regions, but mortality rates decrease as SDI increases. Similar trends were observed for DALYs, with better outcomes in high-SDI regions.
conclusionsSince 1990, childhood leukemia DALYs decreased by 59.03%, with CML showing the largest decline (> 70% in incidence, mortality, and DALYs). ALL remains the most common subtype, with the highest burden in East Asia and Andean Latin America. High-SDI regions report higher incidence but lower mortality, indicating better outcomes than low-SDI regions.
