Hypertension Care Quality and Incidence of Complications Among Hypertensive Patients With Disabilities in Korea: An Analysis of a Cohort Study Using National Health Insurance Data.
Article in Journal of Korean medical science, 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
backgroundHypertension is more prevalent among individuals with disabilities than in the general population. This study analyzed long-term trends in disparities in hypertension care quality and the incidence of hypertensive complications among individuals with and without disabilities.
methodsThis retrospective cohort study followed 52,743 hypertensive patients aged 20 or older with disabilities newly diagnosed in 2010, along with 47,564 age- and sex-matched patients without disabilities, from 2011 to 2019. Hypertension care quality was assessed using indicators of medication adherence and the completion of three complication-monitoring tests at recommended frequency: blood test, urine test, and electrocardiogram (ECG). Hypertensive complications included major cardiovascular and cerebrovascular events, kidney diseases, and all-cause mortality. Logistic regression was repeated annually to assess hypertension care quality, and Cox-proportional model was used to estimate the risk of hypertension-related complications.
resultsHypertensive patients with disabilities consistently demonstrated lower medication adherence throughout the study period (adjusted odds ratio [aOR], 0.90-0.96, depending on the year), but a higher likelihood of undergoing screenings at recommended frequency (e.g., aOR for blood test, 1.31-1.39, for urine test, 1.24-1.33, and for ECG, 1.30-1.37). The risk of complications remained significantly higher among hypertensive patients with disabilities, even after adjusting for care quality indicators (e.g., adjusted hazard ratio for cardiovascular events: 1.36, 95% confidence interval: 1.31-1.41). Subgroup analyses revealed that the excess risks for complications varied across different sociodemographic groups.
conclusionThese findings underscore the need for comprehensive strategies to enhance medication adherence among hypertensive patients with disabilities. Additionally, other factors beyond medication adherence and monitoring test completion that contribute to the increased risk of complications require further exploration.
