*p<0.05 vs. prior to the ingestion period (paired t-test). **p<0.01 vs. prior to the ingestion period (paired t-test). Data are presented as the mean ± standard deviation.
1 BSS scores during only the latter half of each period were used.
2 This subgroup included subjects with a mean BSS score of <4/defaecation during the latter half of the pre-observation period, and the mean BSS score during only the latter half of each period was used.
3 This subgroup included subjects with a mean BSS score of ≥4/defaecation during the latter half of the pre-observation period, and the mean BSS score during only the latter half of each period was used.
Po: pre-observation period; 1 g: 1 g/day ingestion period; W1: washout period 1; 2 g: 2 g/day ingestion period; W2: washout period 2; 3 g: 3 g/day ingestion period.
