Global trends and research hotspots in pulmonary rehabilitation for chronic obstructive pulmonary disease: a bibliometric analysis (2000-2024).
Article in Journal of thoracic disease, 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
Background: Chronic obstructive pulmonary disease (COPD) is a prevalent chronic respiratory disorder characterized by persistent airflow limitation and substantial long-term disease burden. Pulmonary rehabilitation (PR), a cornerstone non-pharmacological intervention in comprehensive COPD management, has undergone sustained expansion over the past two decades in both research volume and intervention paradigms. However, despite the rapid accumulation of evidence, the global research landscape, collaborative structure, and thematic evolution of COPD-related PR remain incompletely characterized. Bibliometric and visualization analyses therefore offer a systematic framework to delineate research patterns, emerging hotspots, and developmental trajectories in this field. This study aimed to characterize the global research landscape, knowledge structure, and research hotspots of pulmonary rehabilitation in COPD from 2000 to 2024 using bibliometric and visualization analyses. Methods: Relevant studies on PR in COPD published between 2000 and 2024 were retrieved from the Web of Science Core Collection (WoSCC). A total of 3,708 English-language publications were included. CiteSpace, VOSviewer, and R-bibliometrix were applied to examine publication trends, international and institutional collaboration networks, co-citation structures, keyword co-occurrence patterns, and thematic evolution. Results: A total of 3,708 publications on PR in COPD were identified between 2000 and 2024. Overall publication output demonstrated a sustained upward trend, whereas international collaboration remained comparatively limited. The United States and the United Kingdom were the leading contributing countries, with the University of Toronto and Maastricht University emerging as the most productive institutions. Anne E. Holland and Martijn A. Spruit were the most prolific authors. High-frequency keywords included PR, exercise training, exercise capacity, and quality of life. Keyword burst analysis further indicated that tele-rehabilitation and integrated multimodal intervention strategies have recently emerged as prominent research hotspots. Conclusions: Over the past two decades, research on PR in COPD has progressively transitioned from predominantly exercise-centered approaches toward multidimensional, digital, and individualized intervention frameworks. This evolution underscores a broader shift toward precision-oriented rehabilitation models and highlights the need for future research to focus on phenotype-informed prescriptions and sustainable long-term management strategies.
