Table 4 Logistic regression models for occurrence of HGD/adenocarcinoma in flat polyps >20 mm

From: Frequent co-occurrence of high-grade dysplasia in large flat colonic polyps (>20 mm) and synchronous polyps

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
