Abstract
Despite the advent of sophisticated imaging systems, plain radiography continues to be a valuable outcome variable in clinical trials of inflammatory disorders for a number of reasons. This paper discusses the pros and cons of the different ways in which radiographic data in trials is presented; the minimum time needed to demonstrate radiographic progression in the context of a clinical trial; and the best ways to statistically analyse radiographic data.
