3.4. Factors associated with BS
REGRESSION
Regarding factors that can affect BS, the time interval from bowel preparation to colonoscopy, the time interval from taking simethicone to colonoscopy, and the level of bowel preparation were considered. A good BS was defined as a total BS score of 7 or higher, and the appropriate time interval from taking simethicone to colonoscopy was defined as <11 hours (i.e., taking simethicone on the day of colonoscopy). Good bowel preparation was defined as a total ABPS score of 8 or less, and the appropriate time interval from bowel preparation to colonoscopy was taken between 3 and 7 hours based on the previous study result.Regression analysis of factors associated bubble score.ABPS = Aronchick Bowel Preparation Score, CI = confidence interval.
