Actual (reported)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."
