Table 1 The number of gastric cancer with successful delineation and successful rate by chromoendoscopy and low-power magnifying endoscopy combined NBI and the highest-power magnifying endoscopy combined NBI in all lesions

From: Highest power magnification with narrow-band imaging is useful for improving diagnostic performance for endoscopic delineation of early gastric cancers
