[Disease burden and risk factors of myocarditis among children and adolescents aged 0-19 years in China from 1990 to 2021 and projection of future disease burden trends].
Article in Zhongguo dang dai er ke za zhi = Chinese journal of contemporary pediatrics, 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
objectivesBased on data from the Global Burden of Disease Study (GBD) 2021, this study aims to analyze trends in myocarditis among children and adolescents aged 0-19 years in China from 1990 to 2021 and predicts the disease burden trends from 2025 to 2050.
methodsData on incidence, prevalence, mortality, and disability-adjusted life year (DALY) of myocarditis in the Chinese population aged 0-19 years were extracted from the GBD 2021 database. Joinpoint regression was used to estimate annual percent change. The GBD comparative risk assessment framework was used to quantify four categories of risk factors: environmental/occupational risks, non-optimal temperature, high temperature, and low temperature. The ARIMA model was applied to forecast the disease burden trends from 2025 to 2050.
resultsFrom 1990 to 2021, the age-standardized prevalence rate of myocarditis in Chinese children and adolescents aged 0-19 years increased, while the age-standardized incidence rate, age-standardized DALY rate, and age-standardized mortality rate decreased. The overall disease burden in China exceeded the global average and that of regions with a middle socio-demographic index. Males had a higher disease burden than females. In 2021, non-optimal temperature and environmental/occupational risks collectively accounted for 66.4% of the disease burden, and DALYs and mortality attributable to high temperature showed an increasing trend. ARIMA model projections indicate that by 2050, the overall incidence of myocarditis will remain stable, whereas DALYs and mortality in the 5-9-year age group are expected to increase among Chinese children and adolescents aged 0-19 years.
conclusionsIn China, the age-standardized prevalence of myocarditis among children and adolescents aged 0-19 years increased continuously from 1990 to 2021, and males had higher values across all burden metrics than females. Projections for 2025-2050 suggest that the overall incidence of myocarditis will remain stable, whereas the disability and mortality burden in the 5-9-year age group will rise. An age- and sex-stratified prevention and control system should be established, and protection against extreme temperatures should be incorporated into the national strategy for children's cardiovascular health.
