Multiple logistic regression analysis adjusting for age and gender to examine risk factors for postcolonoscopy colorectal cancers (PCCRC)
| Postcolonoscopy vs prevalent CRCs* | OR | 95% CI | p Value |
|---|---|---|---|
| Proximal location (vs distal) | 3.92 | 2.71 to 5.69 | <0.001 |
| Size in cm (continuous) | 0.78 | 0.70 to 0.87 | <0.001 |
| Flat appearance (vs protruded) | 1.70 | 1.18 to 2.43 | 0.004 |
| ≥50% mucinous histology (vs <50%) | 1.61 | 0.94 to 2.76 | 0.085 |
| Specialty of endoscopist (gastroenterologist vs non-gastroenterologist) | 1.33 | 0.81 to 2.19 | 0.266 |
| Hospital setting (university vs non-university hospital) | 1.22 | 0.82 to 1.83 | 0.333 |
