A 20-year bibliometric analysis of postoperative pulmonary complications: 2003-2022.
Review in Heliyon, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Background: Postoperative pulmonary complications (PPCs) are known to adversely affect surgical outcomes and patient prognoses, yet no published study provides a qualitative and quantitative analysis of the latest trends and developments in the field of PPCs. Therefore, we conducted a bibliometric analysis of 20 years of publications related to PPCs. Methods: We examined publications on PPCs published between 2003 and 2022 in the Web of Science Core Collection database to assess trends in the field in four dimensions: trends in publications, major research power, keywords, and co-cited publications. Results: A total of 1881 articles were analyzed using CiteSpace and VOSviewer. Overall, the number of publications on PPCs has increased in the last two decades, with 42.72% of the publications being produced in the last five years. The United States of America had the highest number of articles, accounting for 21.91% of the total. The institution with the highest number of publications was the University of Genoa, which published 54 articles and showed a general lack of inter-institutional collaboration. The most productive author was Paolo Pelosi, with no core group of authors identified in the field of PPCs. The keyword co-occurrence analysis indicated that the focus of research has shifted over the past 20 years in terms of risk factors, type of surgery, and so on, while "enhanced recovery", "prehabilitation", "driving pressure" and "sugammadex" have received the most recent attention. In the analysis of co-cited literature, the most recent clusters that received attention were driving pressure, lung cancer patient, enhanced recovery, and neuromuscular blockade. Conclusion: This bibliometric study suggests that pulmonary protective ventilation strategies, neuromuscular blockade reversal, and pulmonary prehabilitation strategy will be the focus of attention in the coming period. More large-scale studies and strengthened institutional collaboration are necessary to generate robust evidence for guiding individualized prevention of PPCs.
