Socioeconomic gradients in hypertension prevalence and management: a cross-sectional study.
Article in BMC public health, 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
backgroundDespite advances in hypertension treatment, achieving optimal blood pressure control remains a major public health challenge. Socioeconomic status (SES) may influence hypertension management; however, evidence on its associations with pharmacotherapy, lifestyle modification, and self-management education remains limited. In this study, the association between SES and hypertension-related outcomes in the Republic of Korea was investigated.
methodsIn this nationwide cross-sectional study, data from the 2023 Korea Community Health Survey were analyzed, comprising 231,584 and 228,608 adults for educational attainment and household income analyses, respectively. Hypertension-related outcomes included diagnosed hypertension, pharmacotherapy, lifestyle modification, and self-management education. Crude and age- and sex-adjusted rates were calculated, followed by multivariable logistic regression analyses, adjusting for potential confounders.
resultsOverall, the prevalence of diagnosed hypertension was 31.3%. Among participants with hypertension, the rates of pharmacotherapy, lifestyle modification, and self-management education were 95.9%, 23.8%, and 15.5%, respectively. The multivariable analyses showed a dose-response relationship between SES and outcomes: participants with primary school education or less had higher odds of diagnosed hypertension (odds ratio, 1.79; 95% confidence interval, 1.71-1.88) and pharmacotherapy use (2.04; 1.67-2.50) but lower odds of lifestyle modification engagement (0.47; 0.43-0.50) and receiving self-management education (0.34; 0.31-0.38) compared to those with college degree or higher. Notably, these socioeconomic gradients remained robustly consistent across all strata, while significantly steeper gradients were observed among females and younger adults (< 65 years). Analyses by household income showed similar patterns of associations, although with slightly weaker magnitudes.
conclusionsLower SES was associated with a higher prevalence of diagnosed hypertension and pharmacotherapy use but lower participation in lifestyle modifications and self-management education. Strengthening tailored self-management education and lifestyle modification support for socioeconomically disadvantaged groups may be an important strategy to reduce hypertension-related disparities.
