Logistic regression models for occurrence of HGD/adenocarcinoma in flat polyps >20 mm
| Multivariate logistic model | |||
|---|---|---|---|
| Parameter | N | OR (lower – upper 95 % CI) | p-value |
| Increase in size of large polyp (per 10 mm) | 355 | 1.29 (1.09–1.55) | 0.0041 |
| Increase in age (per 5 years) | 1.13 (1.00–1.29) | 0.0471 | |
| Female vs. male sex | 1.24 (0.74–2.07) | 0.41 | |
| Location in rectosigmoid colon vs. other location in the colon | 3.89 (2.26–6.79) | <0.0001 | |
| Increase in number of synchronous polyps (per 1 polyp) | 0.95 (0.88–1.01) | 0.10 | |
| Any synchronous polyp with HGD or adenocarcinoma vs. other histology | 3.21 (1.73–6.06) | 0.0003 | |
