Page 4 Left 38th line (original) On magnified observation of NBI, when we observe the lesion at maximum magnification, the length of the corner of the screen is about 0.5 mm, and the length of one side is about 3 mm (Fig. 3).Using this standard, the size of the AVA can be estimated. (revised) On magnified observation of NBI, when we observe the lesion at maximum magnification, the length of one side is about 3 mm, and the length of the corner of the screen is about 0.5 mm (Fig. 3).Using this standard, the size of the AVA can be estimated. Page 4 Right Fig 3. figure legend (original) Fig 3. Estimate the size of AVA. In magnified observation of NBI, when we observe the lesion by the maximum magnification, the length of the corner of the screen is about 0.5mm[A], and the length of one side is about 3mm [B]. Using this standard, we can estimate the size of AVA. (1 scale is equivalent to 1mm.). NBI, narrow band images; AVA, avascular area. (revised) Fig 3. Estimate the size of AVA.
