Data from the National Health and Nutrition Examination Survey (NHANES) from the January 1, 2017, to December 31, 2018, cycle were used to compare the risk profile distribution with that of the general US population.

Among 81\u202f151 individuals with NCS results and 114\u202f302 without endoscopy, 394 and 2229 CRC cases and 167 and 637 CRC deaths, respectively, were documented. Negative colonoscopy screening results were consistently associated with lower CRC incidence (HR, 0.51; 95% CI, 0.44-0.58) and mortality (HR, 0.56; 95% CI, 0.46-0.70) for 20 years. Among individuals with NCS results, those with an intermediate risk (scores, 6-7) and low risk (scores, 0-5) did not reach the 10-year cumulative incidence of CRC (0.78%) of the high-risk individuals (scores, 8-12) until 16 and 25 years after initial screening, respectively.<\/jats:p><\/jats:sec>Conclusion and Relevance<\/jats:title>These findings provide evidence for shared decision-making between patients and physicians to consider extending the rescreening intervals after an NCS result beyond the currently recommended 10 years, particularly for individuals with a low-risk profile.
