Mapping Global Trends and Research Hotspots in Postoperative Depression: A Bibliometric Analysis.
Article in Behavioural neurology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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 bibliometric analysis is aimed at mapping global trends and research hotspots in postoperative depression, providing insights into the evolution and development of research in this field.
methodsA comprehensive search was conducted in the Web of Science Core Collection database, focusing on literature from 1994 to 2024. Data extraction and visualization were performed using VOSviewer (Version 1.6.20), CiteSpace (Version 6.3.R1), and R (Version 4.3.3).
resultsThis study encompassed 687 scholarly articles from 54 countries. The United States contributed the largest number of articles, followed by China and the United Kingdom. High-output institutions from the United States include the University of California System and Harvard University. The Journal of Psychosomatic Research and Epilepsy were among the top journals by h-index. Aalto Timo, Airaksinen Olavi, and Sinikallio Sanna were among the most productive authors. High-frequency keywords included "quality-of-life," "anxiety," and "symptoms." Recent burst keywords "risk," "elderly patients," and "double blind" indicate emerging trends in the field, pointing toward an increased interest in identifying factors that may precipitate postoperative depression, the unique vulnerabilities of older adults, and the methodological rigor of double-blind studies in assessing interventions.
conclusionThe research hotspots and trends in postoperative depression are centered around the impact of depression on surgical outcomes, the role of anxiety, and quality of life assessments. This study reveals a growing interest in predictors of postoperative depression and the exploration of novel therapeutic interventions, indicating an evolving and dynamic research area.
