Detection rate (the detection rate was calculated as the number of individuals in whom colorectal lesions (i.e. cancer, advanced neoplasm or any neoplastic lesion) were detected in each study arm with respect to the number of patients in whom the corresponding lesions were identified at colonoscopy, if a threshold of ≥ 6 mm in size of lesions detected by either CTC or CCE was used to indicate the work-up colonoscopy) of colon capsule endoscopy and CT colonography, according to the intention-to-screen analysis
| Colorectal lesion1 | CCE | CTC | RR | 95% CI | p value |
|---|---|---|---|---|---|
| Cancer | 4 (100%) | 8 (100%) | 1 | 1.00–1.00 | – |
| Advanced neoplasm2 | 43 (100%) | 41 (93.1%) | 1.07 | 0.99–1.16 | 0.08 |
| Any neoplastic lesion3 | 74 (98.6%) | 47 (81.0%) | 1.22 | 1.07–1.38 | 0.002 |
CCE colon capsule endoscopy, CTC CT colonography, RR relative risk, 95% CI 95% confidence interval
1Patients were classified according to the most advanced lesion
2Advanced neoplasm includes invasive cancer, advanced adenomas and advanced serrated lesions
3Any neoplastic lesion includes cancer, advanced and non-advanced adenomas, and advanced and non-advanced serrated lesions
