JADAS-ESR
interphalangeal joints, JIA, active joints, metacarpophalangeal joints
DISEASE
JADAS includes 4 domains: physician global assessment of disease activity (0 means no activity and 10 means maximum activity), parent/patient global assessment of well-being (0 means very well and 10 means very poor), number of active joints, and an inflammatory marker ESR. We used JADAS27 version. The JADAS27 includes a selected count of the following joints: cervical spine, elbows, wrists, metacarpophalangeal joints (from first to third), proximal interphalangeal joints, hips, knees, and ankles. This is based on previous analysis that showed that the 27-joint reduced count is a good surrogate for the whole joint count in JIA [
