Randomised controlled trial comparing modified Sano’s and narrow band imaging international colorectal endoscopic classifications for colorectal lesions

Table 1 Narrow band imaging international colorectal endoscopic classification of colorectal polyps was based on 3 features including colour, vessel, architecture and surface pattern

	NICE I	NICE II	NICE III
Colour	Same or lighter than background	Browner than background	Dark brown relative to background +/- patchy whiter areas
Vessels	None or isolated lacy vessels	Brown vessels surrounding white structures	Disrupted or missing vessels
Surface pattern	Dark or white spots of uniform size, or homogeneous absence of pattern	Oval, tubular or branched white structure surrounded by brown vessels	Amorphous or absent surface pattern
Likely pathology	Hyperplastic	Adenoma	Deep submucosal invasive cancer
