Summary
This study maps global endometriosis research from 1900-2009, revealing the USA as the leading nation in publications and citations. It highlights increasing international collaboration and the need for further investment in endometriosis research.
Area of Science:
- Gynecology
- Medical Research
- Bibliometrics
Background:
- Endometriosis is a common gynecological disease requiring extensive research for diagnosis, therapy, and prevention.
- Despite its prevalence, a comprehensive analysis of the global research landscape for endometriosis is lacking.
Purpose of the Study:
- To analyze the global architecture of endometriosis research.
- To map country-specific publication activities and citation metrics from 1900 to 2009.
Main Methods:
- Utilized the NewQIS platform for a density-equalizing mapping study.
- Analyzed 11,056 endometriosis-related entries from the Web of Science database (1900-2009).
- Created density-equalizing maps focusing on publication counts, citations, citation rates, and h-Indices.
Main Results:
- The USA led in publications (3705), citations (74,592), and h-Index (103).
- The United Kingdom and Japan followed in publication volume.
- Sweden and Belgium showed the highest citation rates, and international collaborations increased significantly in the last decade.
Conclusions:
- This is the first study to illustrate the global endometriosis research landscape.
- Endometriosis research is growing in importance.
- Further investment is crucial to advance endometriosis research and improve patient management globally.
