ABSTRACT:

Background/aims

We aim to investigate the diagnostic accuracy and differences between Chicago classification version 3.0 (CC v3.0) and 4.0 (CC v4.0).

Results

Two hundred forty-four patients were included. The median age was 59 (interquartile range, 45-66) years, and 46.7% were males. Of these, 53.3% (n = 130) and 61.9% (n = 151) were categorized as normalcy by CC v3.0 and CC v4.0, respectively.
