Percentage of Good Responders and Moderate Responders Among Participants With European League Against Rheumatism (EULAR) Response Based on DAS28
The Disease Activity Score Based on 28-joints Count based (DAS28-based) EULAR response criteria were used to measure individual response as none, good, and moderate, depending on the extent of change from baseline and the level of disease activity reached. Good responders: change from baseline \>1.2 with DAS28 =\< 3.2; moderate responders: change from baseline \>1.2 with DAS28 \>3.2 or change from baseline \>0.6 to =\<1.2 with DAS28 =\<5.1; non-responders: change from baseline =\< 0.6 or change from baseline \>0.6 and =\<1.2 with DAS28 \>5.1.
