Research Hotspots and Future Trends of Oxygen Therapy for COPD: A Bibliometric and Visualization Analysis from 1973 to 2024.

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: Oxygen therapy is fundamental in the management of chronic obstructive pulmonary disease (COPD), and its utilization has expanded significantly in recent years. This study aimed to explore global research trends, key contributors, and emerging topics in oxygen therapy for COPD. Methods: Publications concerning oxygen therapy for COPD from 1973 to 2024 were retrieved from the Web of Science Core Collection. A bibliometric analysis was conducted employing VOSviewer, CiteSpace, and R 4.3.3. The contributions of countries, institutions, authors, and journals were systematically assessed. Results: A total of 1,977 publications were analyzed, indicating an annual growth rate of 8.43%. The USA led with 359 publications (18.2%), followed by China with 167 (8.4%) and Italy with 115 (5.8%). The leading institution was Assistance Publique Hôpitaux de Paris, which produced 98 publications. Key journals in this field included Conclusion: Oxygen therapy research for COPD has grown steadily since 1973. Keyword burst and temporal analyses indicate a recent shift of research focus from general oxygen supplementation toward modality-specific and context-specific strategies, including HFNC, exacerbation-related oxygen use, comorbidity-oriented management (eg, COPD-ILD overlap), and respiratory failure-related care, reflecting an increasing emphasis on precision and individualized oxygen therapy.
