| Urticaria Activity Score (UAS28) | n of patients | Mean (SD) | Median | n of patients | Mean (SD) | Median |
| UAS28 ≤ 10 | 55 | 29.1 (3.3) | 30.0 | 55 | 14.1 (2.0) | 15.0 |

| UAS28 = 36-70 | 31 | 20.0 (5.8) | 21.0 | 31 | 8.7 (2.8) | 9.0 |
| UAS28 = 71-105 | 14 | 19.9 (5.0) | 20.0 | 14 | 8.8 (2.2) | 8.0 |
| UAS28 ≥ 106 | 8 | 13.5 (6.9) | 14.0 | 8 | 5.8 (3.1) | 5.0 |
Please note that some correlations show negative values as higher scores of the UCT (well controlled disease) indicates lower disease severity (UAS, PatGA-VAS) and negative impact on healh-related quality of life (CU-Q2oL)
