The detection rate (%) and number needed to scope for colorectal cancer and ⩾1 advanced adenomas focused on the range between 50 and 200 ng ml−1 for males (A) (N=257), for females (B) (N=171), patients <60 years of age (C) (N=252) and for patients ⩾60 years of age (D) (N=175). Left axis: detection rate for colorectal cancer and advanced adenomas (-•-). Right axis: number needed to scope (NNTScope) for colorectal cancer and advanced adenomas (-□-) (by definition ⩾1.0).
