Efficacy of 1.2 L polyethylene glycol plus ascorbic acid for bowel preparations

Figure 3 Difference in the total volume of fluid intake and the required time for bowel preparation between the 1. 2 L polyethylene glycol plus ascorbic acid group and the polyethylene glycol-based electrolyte solution group. A: Total volume of fluid intake. The total volume of fluid intake was significantly lower in the 1.2 L PEG-ASC group than in the PEG-ELS group (2.23 L ± 0.55 L vs 2.47 L ± 0.56 L, P < 0.01); B: Required time for bowel preparation. The required time for bowel preparation was significantly shorter in the 1.2 L PEG-ASC group than in the PEG-ELS group (164.3 min ± 68.6 min vs 203.7 min ± 68.0 min, P < 0.01). PEG-ASC: Polyethylene glycol plus ascorbic acid; PEG-ELS: Polyethylene glycol-based electrolyte solution.
