Assessment

Primary outcomes

The primary outcome variable in this study was the sensitivity of AFI on a per lesion basis.

Key secondary outcomes

(1) The positive predictive value (PPV) of NBI in a per lesion basis; (2) the sensitivity, specificity, PPV, negative predictive value (NPV) and accuracy of AFI in a per patient basis. (3) The differences in sensitivities, specificities, NPVs, PPVs and accuracy with regard to study periods, endoscopists, lesions' size and HGIN or invasive cancer.

Other related information

Initial routine inspection was performed using AFI. Screening with AFI was followed by chromoendoscopy with iodine solution. For all lesions, their location (distance and quadrant) and size were recorded by comparison with the known diameter of open forceps. The lesions detected in each method were matched based on the distance and quadrant of the lesions. Biopsy specimens were taken from iodine-unstained lesions.
