This unique addition to the field of rheumatology focuses on the elements critical for the design and management of clinical trials in rheumatoid arthritis and osteoarthritis...The authors do an excellent job of breaking down how prominent clinical trials designed endpoints, collected and analyzed data, and avoided regulatory hurdles so readers can initiate trials of their own. This is a worthwhile read for those interested in performing clinical trials in either disease...For those without any formal training in clinical research, this book does the trick. -Doody's, reviewed by Alfred H.
