Figure 1
The problem when using a percentage improvement as cut off is illustrated using the DAS28 as single measure of disease activity at baseline and end point of the study. The dark grey area represents low disease activity (according to rheumatologists' treatment decisions), and the lighter grey area represents moderate disease activity. The area of high disease activity is left white. Especially with high disease activity at baseline, a 20% improvement might not be enough, as the reached level of disease activity is still high.
