Figure 2 Receiver-operating characteristic curve of perforation development after endoscopic submucosal dissection. The curve is plotted with sensitivity (y-axis) and (1-specificity) (x-axis). The resulting cut-off value of the procedure time for perforation was 115 min (sensitivity, 87.5%; specificity, 56.7%).
