Figure 2 Successful cleansing rate (BBPS score ≥ 5). The 1.2 L PEG-ASC group was shown to be non-inferior to the PEG-ELS group in terms of successful cleansing rate with a two-sided significance value of 5% and a non-inferiority margin of 10% (1.2 L PEG-ASC group, 91.9%; PEG-ELS group, 90.2%; 95%CI: -0.03-0.09 in the intention-to-treat population).
