Figure 1 The effects of study design and different criterion standards on diagnostic accuracy. A, Diverse criterion standards (dotted rectangles) are externally from affiliated hospitals/clinics and undefined source of follow-up cases after endoscopic submucosal dissection. B, Criterion standards (solid bordered rectangle) are from high-resolution endoscopic biopsy (revised Vienna classification), which is superior to both ultrathin endoscopy (UTE) and standard-resolution endoscopy (SRE) on diagnostic accuracy.
