25 specialists of endoscopy interpret 100 endoscopic images using NBI with or without magnification on the web. Of 100 images, 40 images are for qualitative diagnosis, and 60 images are for quantitative diagnosis.
Endoscopists interpret 100 images with magnification first (Study1). Later, they interpret 100 images without and with magnification (Study2)
