Geographic Age Cohort Study of Maternal Hypertensive Disorders.
Article in Journal of the American Heart Association, 2025. 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
backgroundsMaternal hypertensive disorders (MHDs) remain a critical global health challenge, disproportionately impacting low-resource regions. Using GBD (Global Burden of Disease, Injury, and Risk Factor Study) 2021 data, we first analyze global MHD epidemiology from 1990 to 2021 and project trends to 2035.
methodsAge-standardized rates and estimated annual percentage change quantified incidence, prevalence, mortality rate, and disability-adjusted life years. Trends were stratified by sociodemographic index (SDI) and geography. Decomposition analysis attributed temporal variances (1990-2021) to demographic aging, population dynamics, and epidemiological shifts. Temporal patterns were assessed via age-period-cohort and Bayesian models, while socioeconomic disparities were measured using Slope and Concentration Index of Inequality, and frontier analysis identified SDI-specific optimal burden thresholds.
resultsNew MHD cases rose 15.2% (1990: 15.7 million; 2021: 18.1 million), while deaths and disability-adjusted life years declined by ≈29% (0.038 million deaths; 2.47 million disability-adjusted life years in 2021). Age-standardized incidence fell from 554 to 462 per 100 000 (estimated annual percentage change: -0.51). Sub-Saharan Africa and South Asia bore the highest burden. Higher SDI quintiles demonstrated lower MHD burdens, though all metrics exhibited more pronounced declines in lower-SDI regions during 1990-2021. Women aged 25 to 29 years faced elevated risks, with incidence peaking in this group. Bayesian age-period-cohort modeling projects consistent global declines in incidence, disability-adjusted life years, prevalence, and mortality rates through 2035.
conclusionsDespite progress, inequities in MHD burden persist across SDI levels. Targeted interventions in high-risk regions, particularly enhancing prenatal care access and mitigating age-specific risks, are critical. Strengthening primary health care systems and prioritizing maternal health quality could reduce preventable complications.
