Actual (reported)Reduction in Urticaria Activity Score (UAS7)
Study participants documented their chronic spontaneous urticaria (CSU) symptoms using a diary, daily scoring for a) the number of wheals \[none (=0 points), \<10 (=1 point), 10-50 (=2 points), or \>50 per day (=3 points)\], and b) the intensity of pruritus \[none (=0 points), mild (=1 point), moderate (=2 points), severe (=3 points)\]. The daily UAS score is summed over a week to calculate the UAS7 score (range: 0-42). Participants were considered responders if they had ≥ 95% reduction in baseline UAS7 score and non-responders if they had \<95% reduction in baseline UAS7 score.
