Bowel preparation for colonoscopy using standard vs reduced doses of sodium phosphate: A single-blind randomized controlled study

Figure 3 The mean time required for the completion of the bowel preparation. There was a trend toward a shorter bowel preparation time in the 30 g sodium phosphate (NaP) plus sodium picosulfate group compared to the 50 g NaP group, but this difference was not statistically significant (Student’s t-test, P = 0.065).
