High Eckardt score and previous treatment were associated with poor postperoral endoscopic myotomy pain control: A retrospective study

Figure 5 Calibration plots and receiver operating characteristic curve of the nomogram for prediction. A: The calibration plot is the comparison between predicted and actual outcomes. The dashed line is a reference line, indicating where an ideal nomogram would lie; B: Receiver operating characteristic curve of the nomogram with an area under the receiver operating characteristic curve of 0.822 and an optimal cutoff of 0.730.
