Research frontiers and emerging trends in sex and gender differences in chronic obstructive pulmonary disease: a bibliometric analysis.
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. 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
Background: Numerous studies have examined sex and gender differences in chronic obstructive pulmonary disease (COPD), highlighting their roles in disease susceptibility, hormonal regulation, and inflammation. However, research often conflates sex and gender, and gaps remain in tailored therapies and genetic mechanisms. This study, therefore, employs bibliometric analysis to map the evolution and landscape of this research field. Methods: The authors systematically retrieved literature from the Web of Science Core Collection database, focusing on publications addressing gender differences in COPD between January 1, 2015, and March 4, 2025. The search strategy used the following Boolean query: [TS= ("COPD" OR "Chronic Obstructive Pulmonary Disease") AND ("gender" OR "male" OR "female") NOT ("animal model" OR "cell culture")], adhering to Web of Science Core Collection search syntax rules that ignore case sensitivity but require logical operator capitalisation. Subsequently, bibliometric analyses were performed using CiteSpace 6.3.R1 and VOSviewer 1.6.20. Results: The search identified 493 publications, and the annual output showed a steady rise. De Miguel-Díez J was the most productive author, and CIBER was the leading institution. High-frequency keywords included COPD, respiratory system, gender differences, and prevalence. Recent focus shifted to gender differences and COPD comorbidities. Conclusions: Investigations into sex and gender-specific COPD manifestations have grown in recent years, engaging a growing scientific community. This work systematically synthesises pivotal research trajectories and novel mechanistic insights into gender-differentiated COPD pathology. Future therapeutic strategies for COPD may target the role of sex hormones in pulmonary pathophysiology. The comprehensive summary provides an informative theoretical foundation for researchers and clinical providers and is key to future research tools in this field.
