1 · What the graph read from it

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.

2 · The registry

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

Purpose: Perioperative stroke is a severe postoperative complication increasingly linked to sleep disorders such as insomnia, obstructive sleep apnea (OSA), and circadian disruption. This study aimed to map the global research landscape and identify major trends, collaborations, and evolving themes connecting sleep disorders with perioperative stroke. Methods: Publications from 1999 to 2024 were retrieved from three major databases: WOSCC, Scopus, and PubMed, using combined sleep- and stroke-related search terms. After screening, 1727 eligible articles and reviews were analyzed using VOSviewer, CiteSpace, Bibliometrix, and Scimago Graphica to assess publication growth, co-authorship, institutional productivity, and keyword evolution. Results: A total of 1727 documents from 1,464 journals were authored by 9,643 researchers across 117 countries. The annual growth rate was 7.91%, with an average of 69.53 citations per document. The United States, China, Canada, and the United Kingdom were the leading contributors, while Harvard Medical School ranked first institutionally (72 papers). Keyword and co-citation analyses revealed a thematic evolution, from early circadian and REM-sleep studies to more recent translational research focusing on OSA, cardiovascular risk, and perioperative cerebrovascular events. Conclusion: Research on sleep disorders and perioperative stroke has evolved into a mature, collaborative, and multidisciplinary field. Integrating mechanisms such as inflammation, endothelial dysfunction, and circadian misalignment may enhance perioperative stroke prevention and personalized risk assessment.
