From: 2017 recommendations of the Brazilian Society of Rheumatology for the pharmacological treatment of rheumatoid arthritis

Index Response classification
EULAR-DAS28 response Good: drop ≥ 1.2 points, reaching DAS28 ≤ 3.2
Moderate: drop > 1.2 points, maintenance of DAS28 > 3.2; or drop > 0.6 and ≤ 1.2 points, reaching DAS28 ≤ 5.1
Unresponsive: drop > 0.6 and ≤ 1.2 points, maintenance of DAS28 > 5.1; or drop ≤0.6 points
SDAI and CDAI response Good: drop ≥ 85% in the score value
Moderate: decrease ≥70 and < 85% in the score value
Weak: drop ≥ 50% and < 70% in the score value
Unresponsive: drop < 50% in the score value
  1. CDAI, clinical disease activity index; DAS28, disease activity index (28 joints); SDAI, simplified disease activity index [142,143,144].
