Leveraging National Health Insurance Service Data for Public Health Research in Korea: Structure, Applications, and Future Directions.
Review in Journal of Korean medical science, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 33 papers.
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
The National Health Insurance Service (NHIS) database serves as a crucial resource for public health research in Korea. As a comprehensive dataset within the single-payer healthcare system, NHIS data provides longitudinal insights into healthcare utilization, disease prevalence, and health outcomes. This review article explores the structure, characteristics, and applications of NHIS data, emphasizing its role in epidemiological studies, health policy evaluations, and clinical research. We discuss key methodological considerations, including data access procedures, outcome measures, and strategies to mitigate bias. Additionally, we highlight future directions, such as integrating NHIS data with other national health datasets and utilizing artificial intelligence for predictive analytics. By leveraging the NHIS database, researchers can enhance evidence-based policymaking and improve public health outcomes in Korea.
