Electrolyte changes after bowel preparation for colonoscopy: A randomized controlled multicenter trial

Figure 1 Over-changed electrolytes values.

Figure 2 Study process of enrollment, randomization and analysis of patients assigned to polyethylene glycol with ascorbic acid or 4-L polyethylene glycol. PEG-Asc: Low-volume (2-L) polyethylene glycol solution + ascorbic acid 4.7 g, 4-L PEG: High-volume (4-L) polyethylene glycol solution.

Figure 3 Normal electrolytes levels before and after the intake of bowel cleansing solution. A: Before and after polyethylene glycol solution with ascorbic acid (PEG-Asc); B: Before and after 4-L PEG. P < 0.05, McNemar test was used.
