Regional disparities and hospital performance patterns in acute stroke reperfusion: a multicenter study in Sichuan Province, China.
Article in Frontiers in neurology. 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
Introduction: Timely reperfusion is critical to improving outcomes in acute ischemic stroke (AIS). However, disparities in treatment quality and accessibility persist across hospital levels, regions, and organizational types in China. This study assessed real-world performance of reperfusion care in Sichuan Province. Methods: We conducted a retrospective multicenter study across 33 hospitals in Chengdu from 2021 to 2024. Key process and outcome indicators-including door-to-needle time (DNT), door-to-puncture time (DPT), puncture-to-recanalization time (PRT), intravenous thrombolysis (IVT) within 4.5 h, endovascular treatment (EVT) within 6 h, and in-hospital mortality after EVT-were compared across hospital grades, geographic locations, and stroke center status. K-means clustering was used to explore hospital-level performance patterns based on reperfusion indicators. Results: Door-to-needle time and IVT rates remained relatively high and stable. In contrast, PRT compliance and EVT accessibility showed notable variation. Tertiary A-level hospitals, urban hospitals, and certified stroke centers were associated with higher observed performance in several indicators. EVT-related mortality showed a transient observed spike in non-tertiary A-level and non-stroke center hospitals in 2023. Exploratory cluster analysis identified three hospital-level performance patterns, suggesting persistent disparities in capacity, access, and EVT-related in-hospital outcomes. Conclusion: Our findings highlight institutional and regional inequities in AIS reperfusion care. Stroke center status was associated with higher observed efficiency, accessibility, and EVT-related in-hospital outcome indicators, although residual confounding cannot be excluded. To promote equitable, high-quality stroke care in western China, strategic investments are needed in infrastructure, workforce training, and networked stroke systems, particularly for non-tertiary A-level and non-stroke center hospitals.
