Global trends and geographic variations of hypertension in childhood and adolescence 1990-2021: a systematic analysis of 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: Childhood hypertension is strongly associated with the development of cardiovascular diseases in adulthood. Understanding the epidemiological patterns of disease burden is crucial for developing effective prevention strategies. Methods: This cross-sectional study utilized data from the Global Burden of Disease Study (GBD) 2021, including 204 countries and territories. The analysis estimated deaths, disability-adjusted life years (DALYs), years lived with disability (YLDs), and years of life lost (YLLs) attributable to high systolic blood pressure (sBP) among individuals under the age of 20 within the GBD comparative risk assessment (CRA) framework, covering the period from 1990 to 2021. Trends and regional disparities in disease burden were examined, emphasizing correlations between DALY rates and socio-demographic indices (SDI). Results: In 2021, the global DALY rate was 2.39 (95% uncertainty interval [UI], 1.75 to 2.88) per 100,000 population, representing a 20.11% decrease (95% UI, -35.02 to 10.21) compared to 1990. The YLL rate showed a decrease of 21.06% (95% UI, -36.21 to 9.95), contributing to the decline in the DALY rate, whereas the YLD rate showed an increase of 22.33% (95% UI, 4.16 to 40.74). The DALY rates were negatively correlated with Socio-demographic Index. Among the 21 GBD regions in 2021, Middle East and North Africa (MENA) showed the highest disease burden across all metrics. Western Sub-Saharan Africa (SSA) demonstrated a pronounced gender disparity. High-income North America experienced the largest increase in disease burden. Conclusions: Global DALYs and deaths attributable to high sBP among children and adolescents suggested a declining trend from 1990 to 2021, although the 95% UIs were compatible with no clear change. DALYs showed a negative correlation with SDI, with highest burden in MENA and notable gender disparities in Western SSA. High-income North America showed the largest increase since 1990.
