   description

   The DAS28 score is a measure of the participant's disease activity. It is based on the tender joint count (28 joints), swollen joint count (28 joints), patient's global assessment of disease activity \[visual analog scale: 0=no disease activity to 100=maximum disease activity\], and ESR. DAS28 total scores range from 0 to 10. DAS28 \<=3.2 indicates low disease activity, DAS28 \>3.2 to 5.1 indicates moderate to high disease activity. A negative change from Baseline indicates improvement. The DAS28-based EULAR response criteria were used to measure individual response as none, good, and moderate, depending on the extent of change from baseline (CFB) and the level of disease activity reached. Good response: DAS28 \<=3.2 and a CFB \>1.2. Moderate response: DAS28 \<=3.2 and CFB \>0.6 to \<=1.2, DAS28 \>3.2 to \<=5.1 and CFB \>1.2 or \>0.6 to \<=1.2, DAS28 \>5.1 and CFB \>1.2. No response: DAS28 \<=3.2 and CFB \>=0.6, DAS28 \>3.2 to \<=5.1 and CFB \<=0.6, DAS28 \>5.1 and CFB \>0.6 to \<=1.2 or \<=0.6.
