Varying Rates of Hospital Reperfusion Therapy for Stroke: Insights From Analysis of National Stroke Audit Data.
Article in Journal of stroke, 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
background and purposeDisparities in stroke care exist globally. While reperfusion therapy is a standard treatment for acute ischemic stroke, variations in its implementation may exist across hospitals.
methodsWe analyzed data from 75,870 patients admitted to 247 acute stroke care hospitals across South Korea, sourced from the Acute Stroke Quality Assessment Program (2013-2018) by the Health Insurance Review and Assessment Service. The primary metric of interest was the hospital reperfusion therapy rate (RTR)-the proportion of patients who received intravenous thrombolysis (IVT) and/or endovascular thrombectomy (EVT) among those potentially eligible for these therapies and had onset-to-arrival times ≤6 hours and initial National Institutes of Health Stroke Scale scores ≥4. We analyzed correlations between hospital RTRs, adjusted for age, sex, onset-to-arrival time, initial stroke severity, and hospital characteristics.
resultsOf the 10,513 patients eligible for reperfusion therapy, the overall RTR was 52.9%. The average hospital RTR was 34.8% with a median (interquartile range) of 37.5% (9.8-56.2). Hospitals with a greater number of beds and higher monthly stroke volume exhibited higher hospital RTRs. Factors such as monthly stroke volume, stroke unit availability, and monthly IVT and EVT case volume independently influenced hospital RTRs. Notably, hospitals with higher RTRs demonstrated reduced 1-year mortality, irrespective of stroke volume.
conclusionIn a large national sample of acute stroke care hospitals, there was significant variability in hospital RTRs, with those having higher stroke volumes typically showing higher hospital RTRs. Additionally, an inverse correlation between hospital RTRs and 1-year mortality highlights the clinical importance of improving RTRs.
