Outcome results
Primary
Proportion of Subjects With Successful Bowel Preparation
Successful bowel preparation is defined as a preparation rated as Excellent or Good by the blinded endoscopist on a 4 point scale (Excellent, Good, Fair, Poor).
Time frame: 2 days
Population: Modified intent-to-treat population - subjects who took any portion of the study preparation and did not discontinue due to a reason other than safety, efficacy or tolerability.
| Arm | Measure | Value (COUNT_OF_PARTICIPANTS) |
