Financial Disclosures: The Division of Clinical Pharmacology and Toxicology, University Hospital Basel (Drs Bodmer and Krähenbühl), Basel Pharmacoepidemiology Unit, University of Basel (Drs Brauchli and Meier), and the Boston Collaborative Drug Surveillance Program (Drs Jick and Meier) reported having a research collaboration with various companies in the pharmaceutical industry. Regarding drug companies producing and selling statins, the Basel Pharmacoepidemiology Unit as well as the Boston Collaborative Drug Surveillance Program had or currently have a research collaboration with AstraZeneca and Novartis. The Division of Clinical Pharmacology and Toxicology at the University Hospital Basel currently receives an unconditional grant from AstraZeneca. All of these funded research collaborations are unrelated to this article. We have conducted numerous studies using the UK-based General Practice Research Database in the past, and we are presently working on several projects. Some, but not all of the studies are industry-sponsored. This particular study was not funded. Our group has been conducting research for the pharmaceutical industry for many years, and these collaborations involve numerous companies including Pfizer, Novartis, Bristol-Myers Squibb, AstraZeneca, and Merck Sharp & Dohme. Drs Brauchli, Jick, and Meier reported conducting research related to psoriasis in the past for MerckSerono, Switzerland.
