Analysis of CRC detected in high-risk groups versus CRC diagnosed by colonoscopy results, n (%).
| Colonoscopy | |||||
|---|---|---|---|---|---|
| CRC | Non-CRC | ||||
| High-risk group | CRC | 1515 | 60665 | 62180 | |
| Non-CRC | 478 | 20581 | 21059 | ||
| 1993 | 81246 | 83239 | |||
Sensitivity (Predicting CRC sensitivity in high-risk population)=1515/1993*100%=76.02%; Specificity (Predicting CRC Specificity in high-risk population)=20581/81246 = 25.33%.
