An early indicator of drug success: Top journal Selectivity Index

Abstract

The Top Journal Selectivity Index (TJSI) is a scientometric index reflecting the potential importance of a new drug. It represents the ratio of the number of all types of articles on a particular drug in the top 20journals relative to the number of articles in all (>5,000) biomedical journals covered by Medline over the 5 years since the drug's introduction. The TJSI can be an indicator of a drug's potential for sustained use: a higher score increases the probability of continuing success. © 2013 Kissin, publisher and licensee Dove Medical Press Ltd.
