Transmitted cardiovascular pulsations on high resolution esophageal impedance manometry, and their significance in dysphagia

Figure 2 The receiver operator curve for pressure across pulsatile pressure zone with dysphagia shows area under the curve 0. 65 demonstrating weak significance. Hence even though pressure was a statistically significant variable on Wilcoxon Rank Sum analysis, it is a poor predictor of dysphagia caused by transmitted cardiovascular pulsations on esophagus by this model.
