Landscape and trends in postoperative cognitive dysfunction: A bibliometric and visualized analysis.
Review in Medicine, 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
backgroundPostoperative cognitive dysfunction (POCD) is a hot research topic in the field of anesthesia. Despite decades of research, its pathogenesis remains complex, and worldwide research trends are unclear. We intended to analyze the relevant researches on POCD in the past 30 years by using bibliometric methods.
methodsBased on Web of Science, literature published from January 1, 1993 to December 31, 2022 was retrieved. CiteSpace and VOSviewer were used for descriptive statistical analysis and visualization.
resultsA total of 2290 articles are included, and the number reaches peak in 2022 with 277. China is the country with the largest number of publications, but its centrality is relatively low at 0.06, much lower than that of United States (0.67), which ranks first. Capital Medical University is the institution with the highest number of publications, while Duke University is the institution with the highest centrality. The journal that ranks highest in both citations and centrality is ANESTHESIOLOGY. The most cited literature is Monk TG's research published in ANESTHESIOLOGY in 2008, while Wan YJ's research published in ANESTHESIOLOGY in 2007 has the highest centrality. Research hotspots mainly includes 6 aspects: neuroinflammation, cardiac surgery, delirium, general anesthesia, noncardiac surgery, craniopharyngioma and neuron-specific enolase. Burst keywords analysis reveals that recent studies mainly focus on perioperative neurocognitive disorder.
conclusionThe global research on POCD is growing rapidly. Future studies need to pay more attention to the etiology and mechanism of POCD, and the research on perioperative neurocognitive disorder will still be the frontier hot spot.
