Where Did the Authors Work When They Conducted Their Clinical Pharmacology Studies?

Not yet recruiting

• Conditions: Scientific Collaboration in Clinical Pharmacology

• Registration Number: NCT07115680
• Lead Sponsor: Instituto de Investigación Sanitaria de la Fundación Jiménez Díaz

Brief Summary

It is unknown in which countries the clinical pharmacology studies published in leading specialized journals were conducted. The hypothesis is that studies in this specialty tend to be conducted and published by authors from a single country. This analysis aims to describe the number of collaborators and the countries in which they worked, using the Nature Index concept of "share."

Detailed Description

Original articles (full reports, short communications, research letters) on human participants, data, or material published in the six top (as per Journal Citations Report 2024 Impact Factor) clinical pharmacology hybrid journals linked to clinical pharmacology professional societies will be included. Articles of interest to be included from the June 2025 issue backwards until reaching 100 articles or until the January 2024 issue, whichever comes first. The country of the main authors (first author/last author) and the countries where all the contributors listed in the article's byline worked will be recorded. The contribution of all countries will be calculated using the Nature index's "share" concept. As a proxy, the relevance of each country in contributing to clinical pharmacology research will be calculated by multiplying the "share" score by the impact factor of each journal and adding the scores obtained from the six journals. In addition, following the terminology used by ClinicalTrials.gov, the type of funder will also be recorded to help characterize the studies assessed.
