Association Between Inequality of Emergency Medical Supply Resources and In-Hospital Mortality in Patients With Acute Myocardial Infarction.
Article in International journal of public 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
Objectives: This study aimed to investigate the relationship between regional inequality in emergency medical supply resources and in-hospital mortality among patients with acute myocardial infarction (AMI) in South Korea. Methods: We analyzed data from the Korean National Health Insurance Service claims database, focusing on 53,770 AMI patients admitted to emergency departments between 2012 and 2020. The inequality index of emergency medical supply resources was calculated based on the availability of emergency percutaneous coronary interventions (PCI) within each region. Results: Among 53,770 AMI patients, 4,840 (9.0%) died in-hospital. After adjusting for covariates, patients residing in areas with higher inequality indices had increased risk of in-hospital mortality compared to those in areas with the lowest inequality (index 0.50-0.75: HR 1.504, 95% CI 1.198-1.889; index ≥0.75: HR 1.689, 95% CI 1.493-1.910). Conclusion: This study highlights the importance of equitable distribution of emergency medical resources to reduce in-hospital mortality among AMI patients. Policymakers should prioritize strategies to address regional disparities in emergency medical supply resources to improve health outcomes.
