  1. # DAS28 = 0,56x√TJC28+0,28x√SJC28x0,7xlnESR+0,014xPat global VAS(in mm)
  2. ## SDAI=SJC+TJC+Pat global VAS(in cm)+Eval global VAS(in cm)+CRP(in mg/dL)
  3. ### CDAI = SJC+TJC+Pat global VAS(in cm)+Eval global VAS(in cm)
  4. Cut points for activity states according to various indexes (Panel A) and components of response criteria (Panel B). Yes, required; no, not required; yes/no, in the ACR criteria, 3 of the variables marked "yes/no" are required (0 or 1 laboratory measure). TJC, tender joint count; SJC, swollen joint count; VAS, visual analogue scale; HAQ, health assessment questionnaire.
