Non-Overlapping American College of Rheumatology Response Rates: A Better Way to Report Response in Rheumatoid Arthritis Clinical Trials.

The authors propose a solution to reporting response in rheumatoid arthritis (RA) clinical trials. They consider the success of the American College of Rheumatology (ACR) criteria for 20% improvement in RA disease activity (ACR20) in organizing trial reports and paving interpretation of trial data to direct patient experience. Problems with the classic type of data presentation are discussed. A discussion on the components of the proposed solution is detailed.
