ReviewSleep & breathing = Schlaf & Atmung2026
Research trends and hotspots in stroke-related sleep disorders from 2016 to 2025: a bibliometric and visualization analysis.
Review in Sleep & breathing = Schlaf & Atmung, 2026. 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
backgroundThis study conducted a bibliometric and visualization analysis of research on stroke-related sleep disorders from 2015 to 2026. It aims to elucidate the current research landscape, identify key hotspots, and discern potential future trends within this field.
methodsWe retrieved relevant publications on stroke-related sleep disorders from the Web of Science Core Collection database for the period from January 1, 2016, to December 31, 2025. Using Citespace (Version 6.2.R4), we generated and visualized knowledge maps encompassing analyses of authors, countries, institutions, keywords, co-cited references, co-cited authors, and co-cited journals.
resultsA total of 607 publications were ultimately included. The annual publication count demonstrated a general upward trend over the past decade. Publication output peaked in 2025 with a transient decline in 2019. The United States emerged as the most productive country, followed closely by China. Network analyses revealed strong collaborative relationships among countries, institutions, and authors, shaping influential research clusters represented by scholars such as Devin L. Brown and Ronald D. Chervin. Among institutions, Harvard University contributed the most publications and exhibited a notably high centrality (0.06). Keyword co-occurrence analysis identified eight major thematic clusters and 20 keywords with the strongest citation bursts, with "ischemic stroke" and "apnea" emerging as the predominant core keywords.
conclusionsSleep apnea, particularly obstructive sleep apnea (OSA) and insomnia, remains the most extensively investigated sleep disorder in stroke populations. Hypertension emerged as one of the most frequent keywords among the identified influencing factors. Acute ischemic stroke represented the most common stroke type linked to sleep disturbances. Future investigations are likely to emphasize the identification of underlying pathophysiological mechanisms, systematic exploration of influencing factors, and the development of robust risk prediction models, ultimately aiming to inform clinical decision-making and improve long-term patient outcomes.
