- Brief Summary
There was no significant difference in the rate of accurate diagnosis of cancerous versus non-cancerous lesions between the still image and the moving image tests (59.9% versus 61.4%). However, the diagnostic accuracy were significantly lower in the still image test than the moving image test in the subgroup of board-certified endoscopists (62.5% versus 66.5%, p=0.04), the subgroup of endoscopists who had experienced more than 200 M-NBI procedures (65.6% versus 68.9%, p<0.05), and the subgroup of endoscopists who had experienced more than 15 M-NBI procedures in the previous month (65.1% versus 69.3%, p=0.04).
