Cardiovascular disease risk disparities between immigrants and native Koreans: a population-based study in Gwangju, Korea.
Article in Epidemiology and health, 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
objectivesKorea is becoming a multiethnic society, with immigrants comprising nearly 5% of the population. Evidence on cardiovascular disease (CVD) risk among immigrants remains limited.
methodsWe conducted a population-based study of 582 immigrants in Gwangju and 2,328 age-matched and gender-matched native Koreans (2022-2023). Immigrant data were obtained from direct health assessments, while native Korean data were drawn from the Korea National Health and Nutrition Examination Survey. CVD risk was estimated using the Framingham risk score (FRS) and pooled cohort equations (PCE). Logistic regression was employed to compare the odds of elevated risk (10-year CVD risk ≥7.5%), adjusting for socio-demographic and behavioral factors.
resultsImmigrants had a higher prevalence of hypertension (37.3 vs. 16.1%), diabetes (11.5 vs. 5.6%), poor self-rated health (69.6 vs. 61.3%), and unmet medical needs (30.9 vs. 8.9%), as well as lower rates of health checkups and cancer screening (all p<0.001), compared to native Koreans. Elevated CVD risk was more frequent in immigrants (FRS, 31.4 vs. 20.8%; PCE, 33.6 vs. 22.8%). The adjusted odds ratios (95% confidence intervals) were 1.47 (1.14 to 1.88) for FRS and 1.49 (1.07 to 2.08) for PCE. Disparities were greatest among women, adults ≥40 years, uninsured people, low-income groups, and migrants from Central Asia, Russia, and Africa.
conclusionsImmigrants in Korea face substantially higher CVD risk than native Koreans, particularly within socioeconomically vulnerable subgroups. Targeted prevention and policies addressing structural barriers are urgently needed.
