Multicenter, randomized study to optimize bowel preparation for colon capsule endoscopy

Figure 1 Patient flow diagram. ¹Group A received any of the CCE preparation regimen = Baseline subject characteristics, safety analysis, comparisons between Control regimen and Rex et al[1] and between Study regimen and Spada et al[15] for colon capsule completion and transit times. ²Group B excluded subjects who withdrew before capsule ingestion, had a protocol violation, or experienced technical failure of the capsule = Colon cleansing by segment, CCE completion, CCE transit times, polyp detection by colon segment, comparisons between Control regimen and Rex et al[1] for colon cleansing by segment. ³Group C excluded subjects listed above (B), and those with non-visualization of the cecum, right colon, or transverse colon = Colon cleansing for whole colon, polyp detection for the whole colon, comparisons between the Control regimen and Rex et al[1] and between the Study regimen and Spada et al[15] for overall cleansing of the colon. ⁴Group D excluded subjects listed above (B and C) and those with both inadequate overall colon cleansing and colonic transit time < 40 min = Comparisons between Control regimen and Rex et al[1] and Study regimen and Spada et al[15] for whole colon polyp detection.
