Table 3 Polyp categorization according to Sano’s classification - Hyperplastic/SSA/P vs adenoma/cancer

	Pathology		Total
	Hyperplastic/ SSA/P	Adenoma/cancer
Sano’s classification
I	245	24	269
II, IIIa, IIIb	36	555	591
Total	281	579

Sensitivity of predicting adenoma = 95.7% (93.4% to 97.2%); Specificity of predicting adenoma = 86.5% (81.7% to 90.2%); PPV of predicting adenoma = 93.9% (91.7% to 95.6%); NPV of predicting adenoma = 91.0% (86.4% to 94.0%).
