Subtype and gender-differentiated burden of stroke in China (1990-2021): attributable risk factors and future projections based on 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
Introduction: Using data from the Global Burden of Disease Study 2021 (GBD 2021), this study analyzed the 32-year trends (1990-2021) of stroke burden in China, quantified the attributable risk factors, and projected the future trajectories (2022-2035) of stroke and its subtypes. It also emphasized subtype- and gender-specific disparities to provide evidence for precision prevention. Methods: Age-standardized incidence rate (ASIR), prevalence rate (ASPR), mortality rate (ASMR), and disability-adjusted life years rate (ASDR) of stroke were analyzed using estimated annual percentage change (EAPC) and Joinpoint regression. The population attributable fraction (PAF) was used to quantify the burden of stroke-related disability-adjusted life years (DALYs) attributed to risk factors, and Bayesian age-period-cohort (BAPC) modeling was applied to project future burden. Results: In 2021, the ASIR, ASPR, ASMR, and ASDR of stroke in China were 204.75, 1301.42, 138.03, and 2,648.02 per 100,000 populations, respectively. From 1990 to 2021, ASMR (EAPC = -1.92; 95% CI: -2.17 to -1.67) and ASDR (EAPC = -2.05; 95% CI: -2.25 to -1.86) of stroke decreased, while ASPR increased (EAPC = 0.34; 95% CI: 0.31 to 0.38). Subtype analysis showed opposing trends: IS ASIR (EAPC = 0.94; 95% CI: 0.88 to 1.00) and ASPR (EAPC = 1.02; 95% CI: 0.96 to 1.08) increased, whereas ICH and SAH burdens decreased (ICH ASIR EAPC = -2.24; SAH ASIR EAPC = -3.70). Males had higher ASRs than females in 2021, except for ICH ASPR. High systolic blood pressure (PAF = 56.04%), ambient particulate matter pollution (PAF = 24.37%), and smoking (PAF = 17.91%) were the top three risk factors for stroke-related DALYs; high LDL cholesterol (PAF = 28.42%) ranked second for IS. Projections indicated that by 2035, overall stroke ASIR (from 208.27 to 194.07 per 100,000) and ASMR (from 139.94 to 100.34 per 100,000) would decrease, but IS ASIR would rise to 156.44 per 100,000 (from 139.98 per 100,000 in 2022). Conclusions: The stroke burden in China shows a downward trend, with a subtype-specific feature of increasing IS and decreasing ICH/SAH. High systolic blood pressure is the potential risk factor for stroke, with variations across subtypes and genders. Targeted interventions such as smoking control for males, sodium intake reduction for females, and LDL cholesterol management for IS, are urgently needed to mitigate the future IS burden.
