Trends and interrupted time series analysis of congenital heart disease mortality among the Chinese population aged 0-64 years, 2002-2021.
Article in PloS one, 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
objectivesOur study aimed to analyze congenital heart disease (CHD) mortality trends among Chinese residents aged 0-64 years from 2002 to 2021 and assess the impact of implementing the medical insurance policy (MIP) for rural children on CHD mortality.
methodsData on CHD mortality in urban and rural regions of China from 2002 and 2021 were collected from the China Health Statistics Yearbook. Because mortality data for individuals aged ≥65 years were incomplete and lacked specificity for CHD, the analysis was restricted to those aged 0-64 years. Joinpoint regression was used to analyze trends in CHD mortality by region, sex, and age group, and interrupted time series analysis was used to evaluate the impact of the MIP on CHD mortality.
resultsBetween 2002 and 2021, the standardized CHD mortality among Chinese residents was higher in rural areas than in urban areas, and higher in males than in females. CHD mortality for rural and urban residents declined at an average annual percentage change (AAPC) of -3.63% (95% CI: -4.84% ~ -2.40%) and -4.99% (95% CI: -8.38% ~ -1.47%), respectively. Male mortality decreased more than female mortality. Mortality in the < 1, 1-4, 5-9, 35-39, and 40-44 age groups have been declining over the past 20 years; Furthermore, CHD mortality in rural areas has gradually decreased since the implementation of MIP (β3 = -0.073,95% CI: -0.100 ~ -0.045).
conclusionsIn China, CHD mortality declined from 2002 to 2021, with variations still present based on gender, age, and region. Future prevention and control measures should be strengthened for specific populations in different regions.
