  • Model 1: Objective outcomes*: psoriasis, nail pitting, dactylitis, arthritis, enthesitis, and sacroiliitis. Improved in < 5 from the following variables: psoriasis, nail pitting, dactylitis, arthritis, enthesitis, and sacroiliitis. Improved in ≥ 5 from the following variables: psoriasis, nail pitting, dactylitis, arthritis, enthesitis and sacroiliitis.

  • Model 2: Health questionnnaire (HQ) outcomes**: 4 HQ (PAINSC, HRQOL, GLASWBSC, and PGA). Improved in < 4 HQ (PAINSC, HRQOL, GLASWBSC, and PGA). Improved in all 4 HQ (PAINSC, HRQOL, GLASWBSC, and PGA). NS: nonsignificant; PGA: physician global assessment; DMARD: disease-modifying antirheumatic drug; GC: glucocorticosteroids; NSAID: nonsteroidal antiinflammatory drugs; bDMARD: biologic DMARD; HRQOL: health-related quality of life; PAINSC: parent/subject pain scale; GLASWBSC: parent/subject overall well-being.
