A successful BM was defined as a BM with no straining or hard/lumpy stools.

The VAS is a psychometric response scale which measures responses along a continuum of values. The BM control VAS uses a 100 mm horizontal line with the two ends representing the opposite, extreme limits of the participant's experience of BM control. Participants marked where they felt they resided between the two ends with a vertical line. The distance from the left end of the VAS (0 mm) to the participant's mark was measured and recorded in mm. BM Control ratings ranged on a continuous scale from 0 to 100 mm, where 0 mm=Calm, not urgent and 100 mm= Not able to hold BM, very urgent.

Participants completed a VAS after every BM or attempted BM. The VAS ratings recorded in the diaries for each BM were averaged (with range) to yield a single score for each participant. Participant scores were then averaged by treatment group

The Gas VAS uses a 100 mm horizontal line with the two ends representing opposite, extreme limits of the participant's experience with BM-related gas. Participants marked where they felt they resided between the two ends with a vertical line. The distance from the left end of the VAS (0 mm) to the participant's mark was measured and recorded in mm.

At the End of Study Visit, the study staff asked the participant to rate their global assessment of the study treatment according to the following categories: 0 = not at all effective, 1 = a little bit effective, 2 = moderately effective, 3 = quite a bit effective, 4 = extremely effective.

Participants received Polyethylene Glycol plus Electrolytes (PEG+E) as three sachets of PEG+E (39.375 g) dissolved in 375 mL of non-carbonated water ingested orally with entire volume taken at one time on the day of open-label treatment.

Time to first successful bowel movement was defined as the duration (in days) from the time of first study dose of study treatment until first successful BM (defined as BM without straining and without hard and/or lumpy stool).

Participants in the ITT Population (defined as all participants who were randomized regardless of whether they had taken study treatment) who had a successful bowel movement (no straining or hard/lumpy stools). Participants who reported no successful BMs were censored.

The treatment success rate was calculated as the number of participants in a treatment group with treatment successes (BM with no straining or hard/lumpy stools) divided by the total number of participants in the treatment group. Treatment success rate was calculated for each dose group along with 95% confidence intervals (CI) based on exact binomial statistics. Treatment success rates were compared between each pair of treatments using an exact 2-sided test (Fisher's).

Logistic regression analysis was performed with treatment success as the dichotomous dependent variable and dose (13.125g, 26.25g, or 39.375 g) as the independent variable. The main effects for the model were tested for significance at the 5% level.

The odds of response for the 26.25 g dose level versus the 13.125 g dose level were presented together with the associated 95% confidence intervals. There were no multiplicity adjustments.
