*P value was adjusted by Bonferroni adjustment.
†Stool consistency was recorded by Bristol Stool Form Scale [25], ranging from 1 (separate hard lumps, like nuts) to 7 (watery, no solid pieces).
‡Stool amount was classified into three categories (small, <250 g; moderate, 250–500 g; large, >500 g) according to a national guidelines of the Registered Nurses Association [24].
