Fig. 2From: Predictive factors for esophageal stenosis in patients receiving prophylactic steroid therapy after endoscopic submucosal dissection for esophageal squamous cell carcinomaKaplan–Meier curve for the withdrawal rate of EBD after ESD. The withdrawal rates of EBD in the NRF and RF groups 1 year after ESD were 86.5% (77/114) and 38.3% (26/59), respectively, and 3 years after ESD were 96.1% (52/53) and 58.5% (39/59), respectively.
