a
P-values were obtained by comparison among the three groups using a χ2 test (for gender) or one-way analysis of variance (for other parameters).
b
M, male; F, female.
c
Statistically significant differences. Values are presented as the mean ± standard deviation. TEWL, transepidermal water loss; group P, placebo group; group L, 25 mg/day heat-killed L. brevis SBC8803 group; group H, 50 mg/day heat-killed L. brevis SBC8803 group; a.u., arbitrary unit.
