Comparison of diagnostic accuracy for white light, autofluorescence and magnifying endoscopy with narrow band

Method	WLI	AFI	ME-NBI
Sensitivity	81.5%a	81.5%a	100%
Specificity	61.7%b	14.9%bd	97.9%
Accuracy	68.9%b	39.2%bd	98.6%

^aP = 0.02,

^bP < 0.01 vs magnifying endoscopy with narrow band imaging (ME-NBI);

^dP < 0.01 vs white light imaging (WLI). AFI: Autofluorescence imaging.
