Visualizing Three Decades of Chronic Obstructive Pulmonary Disease and Airway Mucus Hypersecretion Research: A Bibliometric Analysis (1994-2024).
Article in Tuberculosis and respiratory diseases, 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
backgroundChronic obstructive pulmonary disease (COPD) is a condition with high prevalence and mortality, causing a substantial disease burden. Airway mucus hypersecretion (AMH) is clinically associated with impaired pulmonary function, diminished quality of life, and increased mortality in COPD patients. The purpose of this bibliometric research was to identify research developments and emerging hotspots within the field of AMH and COPD by providing a comprehensive overview of the current research landscape.
methodsThe Web of Science core database was searched for publications addressing COPD and AMH from January 1, 1994, to December 31, 2024. A total of 1,405 publications were retrieved and subjected to bibliometric and visual analyses using CiteSpace, VOSviewer, and R software.
resultsFrom 1994 to 2024, both publication output and citation frequency in this field demonstrated a sustained upward trajectory. The United States of America occupies a prominent position in this domain, characterized by substantial collaborative networks and research productivity. While extensive inter-country and interinstitutional collaborations were evident, researcher-level collaborations remained relatively fragmented. Notably, Boucher, Richard C. received substantial recognition owing to his exceptional research productivity and citation impact. Keywords including exacerbations, autophagy, and mucus plugs exhibited the strongest citation bursts during 2023-2024.
conclusionThis research illustrates the present landscape, focal points, and future directions in the fields of COPD and AMH. Researchers may benefit from obtaining a rapid synopsis, along with citations and innovative concepts, to facilitate and inform subsequent investigations.
