Each value (g/m2h) represents the mean ± standard deviation, and the difference from the screening value is shown in parenthesis.
a
P<0.05
b
P<0.01 by intragroup comparison using paired Student's t-test.
c
P<0.1 by by intergroup comparison using Dunnett's test using the value of group P as a reference. 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; L. brevis, Lactobacillus brevis.
