The time to recovery was defined as the time from baseline to a clinical status score of 1 or 2 on the 7-category ordinal scale (whichever occurs first); clinical status scores are defined as follows: 1. Discharged (or "ready for discharge" as evidenced by normal body temperature and respiratory rate, and stable oxygen saturation on ambient air or ≤2 Litres supplemental oxygen); 2. Non-Intensive Care Unit (ICU) hospital ward (or "ready for hospital ward") not requiring supplemental oxygen; 3. Non-ICU hospital ward (or "ready for hospital ward") requiring supplemental oxygen; 4. ICU or non-ICU hospital ward, requiring non-invasive ventilation or high-flow oxygen; 5. ICU, requiring intubation and mechanical ventilation; 6. ICU, requiring extracorporeal membrane oxygenation (ECMO) or mechanical ventilation and additional organ support (e.g., vasopressors, renal replacement therapy); 7. Death.

The Eczema Area and Severity Index (EASI) is a standardized instrument to evaluate the extent and severity of atopic dermatitis. An area score comprised of the percentage of skin affected by eczema for each of 4 body regions (head/neck, trunk, upper extremities, and lower extremities) is calculated with 0 = none, 1 = 1-9%, 2 = 10-29%, 3 = 30-49%, 4 = 50-69%, 5 = 70-89%, and 6 = 90-100%. Severity is scored for each of the 4 body regions by the summation of the intensity scores for 4 signs (redness, thickness, scratching, and lichenification), with 0 = none/absent, 1 = mild, 2 = moderate, and 3 = severe. The minimum final EASI score is 0 and the maximum score is 72.

Asthma exacerbation was defined as new or increased asthma symptoms (wheezing, coughing, dyspnea, chest tightness, and/or nighttime awakenings due to these symptoms) that result in one or both of the following: Hospitalization or emergency department visit with administration of systemic corticosteroid treatment; Treatment with systemic corticosteroids for at least 3 days, or a long-acting depot corticosteroid preparation with a therapeutic effectiveness of at least 3 days. Adjusted rates for the overall mITT population (all participants that received at least one dose of study drug) were estimated using Poisson regression and adjusted for blood eosinophil level at the first visit, the number of asthma exacerbations requiring systemic corticosteroids in the 12 months prior to study entry, the total daily ICS dose at the first visit, and geographic region, with patient time at risk used as an offset term.
