Fig. 1. The colonoscopic findings of 25 advanced CRNs in false-negative groups. An advanced CRN was expressed as a circle, whose size depends on the size of the CRN and whose location corresponds to the location of the CRN. Moreover, an open circle represents a polypoid configuration whereas a closed circle represents a nonpolypoid configuration. Advanced CRNs were located in the right colon in 52% (n = 13) and in the left colon in 48% (n = 12). Most (88%) of them displayed polypoid configurations; only 12% (n = 3) of them had nonpolypoid configurations.
