Table 2 The successful rate in each macroscopic type by chromoendoscopy and low-power magnifying endoscopy combined NBI and the highest-power magnifying endoscopy combined NBI

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