To evaluate the effectiveness of twice daily soak-and-seal baths for improving severity of disease in children with AD, we implemented a randomized clinical trial using a single-blind, crossover-controlled design. Patients received the same moisturizer, cleanser, and class VI topical corticosteroid (TCS), and only bathing varied. After a 1 week run-in, children were randomized 1:1 into 2 groups: Group 1 underwent twice weekly soak-and-seal baths for 2 weeks ("dry method") followed by twice daily soak-and-seal baths for 2 weeks ("wet method"), and group 2 did the converse. A single treating physician assessed outcomes and, along with those analyzing the data, was masked to group assignment. Participants and their caregivers could not be masked. Analyses were based on intention to treat.
