β—standardized regression coefficient (reference category: without kefir intake), p < 0.05 for statistical significance. Model 1—kefir Status; Model 2—kefir status, skin status; Model 3—kefir status, skin status, gender; water intake. (**) Variable skin status was excluded from the models. n.a.—not applicable. a—gender and water contribution showed p < 0.05. TEWL—transepidermal water loss. SCORAD—SCORing of Atopic Dermatitis.
