Discrepancies in tuberculosis burden estimates: North Korean defectors vs. official reports.
Article in Frontiers in public health, 2025. 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
Objectives: North and South Korea have taken different approaches to tuberculosis (TB) epidemic control after the Korean War. This study aimed to compare TB epidemiology in North Korean defectors (NKDs) based on South Korean National Health Insurance (NHIS) data and assess its implications for understanding TB prevalence in North Korea. Methods: We used the NHIS claims data from 2007 to 2019 to evaluate TB epidemics in NKD and the age-and-sex matched South Korean control group. The number of participants was 35,620 for defectors and 107,016 for the control group. Results: The prevalence of TB among NKDs decreased from 466/100,000 persons in 2010 to 95/100,000 persons in 2019, while the North Korean TB prevalence as per the World Health Organization (WHO) report remained approximately 500/100,000 persons. The NKD TB prevalence was 3-7 times higher than that in the South Korean population. Additionally, the distribution of TB cases in NKDs showed distinct age-related patterns, with peaks in the 25-34 and 65 + age groups. The proportion of extrapulmonary TB in NKDs was 36-46%, similar to South Korean patterns. The estimated and reported multidrug-resistant TB rates in NKDs were higher than in the control group, highlighting potential underreporting in North Korean data. Conclusion: There were large gaps in TB prevalence between NKD and native North Korean residents and between the estimated and reported TB burden within North Korea. These findings underscore the need for targeted TB control strategies that address both health system disparities and the integration of NKDs into local healthcare services.
