Table 2 Diagnostic value of colorectal lesions (For distinguishing intramucosal lesions/SM superficial cancer from SM deep cancer)

	Sensitivity	Specificity	Negative predictive value	Positive predictive value	Accuracy
Diagnosis based on the color analysis	80.00%	84.40%	29.60%	98.10%	84.10%
Diagnosis based on the endoscopic findings¹	60.00%	100%	100%	96.80%	84.10%

¹Using magnifying endoscopy with narrow band imaging and/or chromoendoscopy. Submucosal (SM) superficial cancer: Submucosal invasion was defined as less than 1000 μm from the muscularis mucosae; SM deep cancer: Submucosal invasion was defined as 1000 μm or more from the muscularis mucosae.
