Table 4 Outcome (percentage) that would have been detected using the model if colonoscopy restricted
Group to which colonoscopy restricted | Cancer (%) | Advanced Adenoma (%) | Adenomas 6 - 9 mm (%) | Adenomas ≤ 5 mm (%) |
|---|---|---|---|---|
Aged 40+ (89.5% of patients) | 100.0 | 97.0 | 97.2 | 97.4 |
Top 89.5% predicted probability of cancer from model | 98.7 | 96.8 | 93.0 | 92.5 |
Aged 60+ and no previous colonoscopy (16% of patients) | 49.1 | 28.2 | 20.6 | 18.9 |
Top 16% predicted probability of cancer from model | 64.8 | 28.2 | 16.8 | 17.8 |
