Narrow-band imaging-modified Kyoto score predicts pathological upgrading after endoscopic submucosal dissection in gastric intraepithelial neoplasia

Figure 1 Flowchart of the study. GIN: Gastric intraepithelial neoplasia; EFB: Endoscopic forceps biopsy; ESD: Endoscopic submucosal dissection; LGIN: Low-grade intraepithelial neoplasia; HGIN: High-grade intraepithelial neoplasia; EGC: Early gastric cancer.
