Evaluation of a telemedicine pilot project for hypertension in Korea: a nationwide real-world data study.
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
objectivesA telemedicine pilot project has received temporary authorization in Korea. The clinical effectiveness of telemedicine is well established; however, ongoing research must assess medical utilization, sustainability, prescription continuity, and safety.
methodsThis study evaluated medical utilization, sustainability, prescription continuity, and safety before and after the implementation of a telemedicine pilot project between June 2022 and December 2023. Data were obtained from the Korean National Health Insurance Service (NHIS), and participants were divided into those who received non-face-to-face hypertension treatment at least once and those who did not.
resultsThis study included 124,210 patients diagnosed with hypertension who received telemedicine (the Tele_G group) and 124,210 propensity score-matched control individuals. The difference-in-difference (DID) for medical utilization between the Tele_G and control groups was 0.10 (-0.03 vs. -0.12, p<0.001). The DID for the Modified Modified Continuity Index was -0.005 (-0.003 vs. 0.002, p<0.001), while that for Most Frequent Provider Continuity was -0.006 (-0.004 vs. 0.002, p<0.001). The DID for the prescription day rate was 0.41 (-0.61 vs. -1.02, p<0.001), and that for the appropriate prescription continuation rate was 0.52 (-1.23 vs. -1.75, p<0.01).
conclusionsTelemedicine did not fully achieve the same standard as face-to-face treatment for hypertension management; however, it showed comparable safety, suggesting potential as secondary care. As the first NHIS-based study on this topic in Korea, this research highlights the benefits of telemedicine when appropriately utilized for patients with hypertension. Nevertheless, due to limitations regarding long-term continuity and policy design, cautious interpretation is required, and further prospective studies are warranted.
