Medical scientific publisher Informa Healthcare, UK, has announced highlights of its latest journal Impact Factor results, with impressive results across the division's comprehensive range of titles. Impact factors are a method of measuring the influence which a journal has on the scientific community. They are calculated by Thomson Reuters and are designed to indicate how many times the published articles of a journal are cited during the course of a year, providing an insight to how much 'impact' the journal is making on its audiences.
Informa Healthcare's highly respected range of Expert Opinion titles performed notably well, with significant jumps for Expert Opinion on Biological Therapy which is up almost 20 percent to 3.475 and Expert Opinion on Therapeutic Targets, up more than 21 percent to 4.038. Expert Opinion on Investigational Drugs led the series with a 2008 Impact Factor of 4.058. Two new titles - Expert Opinion on Drug Safety and Expert Opinion on Metabolism & Toxicology - registered first ever Impact Factors of 3.073 and 3.069, respectively.
The company's Critical Reviews in Toxicology registered an impact factor of 7.204, up more than 40 percent and now ranked 2nd out of 75 journals in toxicology.
