The variables of the model proposed by Saccomanno, et al1 in the cohort of patients with systemic juvenile idiopathic arthritis treated with anakinra. Data are n (%).
| Variables | Complete Responders, n = 28 | Nonresponders, n = 17 | p |
|---|---|---|---|
| Disease duration ≤ 3.9 yrs | 22 (78.6) | 11 (68.8) | 0.72 |
| Active joint count ≤ 10 | 27 (96.4) | 14 (82.4) | 0.14 |
| Ferritin > 444 ng/ml | 25 (89.3) | 3/12 (25) | < 0.001 |
| Systemic manifestation score > 3 | 24 (85.7) | 8 (47.1) | 0.008 |
| Meeting all 4 variables of the proposed model | 19 (67.9) | 1/12 (8.3) | 0.001 |
