Impact of health insurance status on hospitalization and mortality from emergency department admission in patients with end-stage kidney disease: a Korean nationwide registry analysis.
Article in Kidney research and clinical practice, 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
backgroundHealth insurance plays a critical role in healthcare accessibility and outcomes, particularly for patients with end-stage kidney disease (ESKD). This retrospective observational study evaluated the relationships between health insurance status and rates of hospitalization and in-hospital mortality among patients with ESKD visiting the emergency department (ED).
methodsWe retrospectively analyzed data from the National Emergency Department Information System in South Korea from January 2018 to December 2021. Patients were identified on the basis of their ICD-10 codes (N18.5) and categorized by health insurance type (Medical Aid [MA] recipients vs. National Health Insurance [NHI] beneficiaries). The primary outcomes were rates of hospitalization and in-hospital mortality from ED admission. Multivariate logistic regression models were used to assess the associations between insurance type and outcomes.
resultsAmong the 157,794 ED visits, 23.5% were by MA recipients and 76.5% by NHI beneficiaries. The participants in the MA group were younger than those in the NHI group, and the proportions of females and those with severe disease were lower in the MA group. After adjusting for age, sex, and the Korean Triage and Acuity Scale score, the MA group had a lower hospitalization risk but a risk of death similar to that of the NHI group. Patients <60 years of age had a lower hospitalization rate but a higher in-hospital mortality.
conclusionYoung, economically active MA patients were less likely to be admitted but had poor clinical outcomes after admission, suggesting their reluctance toward hospitalization for economic reasons.
