Study Arms:
- Mixture of three Bifidobacteria (Type: ACTIVE_COMPARATOR): Patients were administered 1 sachet per day of a mixture of three Bifidobacteria (namely, 3 billions of Bifidobacterium longum BB536®, 1 billion of Bifidobacterium infantis M-63®, and 1 billion of Bifidobacterium breve M-16V®) for six weeks. Subsequently, no preparation was administered for a 2-week-''washout'' period. At each follow-up visit subjects underwent a complete physical examination, data recorded on the daily diaries were collected and compliance to treatment was verified.
- Placebo (Type: PLACEBO_COMPARATOR): Patients were administered 1 sachet per day of placebo for six weeks. Subsequently, no preparation was administered for a 2-week-''washout'' period. At each follow-up visit subjects underwent a complete physical examination, data recorded on the daily diaries were collected and compliance to treatment was verified.

Based on this trial design, predict the completion outcome and termination type (if applicable).
