Change From Baseline in Urticaria Activity Score 7
Tidsramme: Baseline, Day 14, and Day 28
|
Urticaria Activity Score 7 (UAS7) was calculated from daily wheal and itch scores over 7 consecutive days.
The total score ranges from 0 to 42, with lower scores indicating lower urticaria activity.
The secondary endpoint was within-participant change from baseline after 28 days of product intake.
