Nationwide Trends and Future Projections of Diabetes and Diabetic Retinopathy Prevalence in Korea: Korean National Health and Nutrition Examination Survey Study.
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. Cited by 1 paper.
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
backgroundThe prevalence of diabetes mellitus (DM) and diabetic retinopathy (DR) is expected to increase globally; however, there have been no reports predicting DR prevalence in Korea. This study aimed to estimate the nationwide trend of the prevalence of DM and DR in Korea.
methodsDiabetic patients aged over 40 were included from the Korean National Health and Nutrition Examination Survey database (2008-2020). The prevalence of DM and DR during the study period was calculated. Four interpolation methods were applied to address the missing DR data (2013-2016), and the method with the smallest error was selected for projection. Holt's linear trend model was used to predict DM and DR prevalence through 2040. We further projected the future number of DR patients in Korea using population projections.
resultsWe included 8,007 diabetic patients aged 40 years or older and 4,540 individuals with fundus photography results. The prevalence of DM increased from 13.2% in 2008 to 17.3% (4.98 million) in 2020, while the prevalence of DR rose from 16.6% in 2008 to 24.6% (1.23 million) in 2020. The projected prevalence of DM is estimated to reach 19.7% in 2030 and 23.0% in 2040, while DR prevalence is expected to rise to 30.8% (1.97 million) in 2030 and 38.8% (3.15 million) in 2040.
conclusionThe prevalence of DM and DR, as well as the number of patients, have increased over 13 years, and this trend is projected to continue through 2040 in Korea. Therefore, it is essential to establish effective healthcare strategies to address this trend.
