Comparison of Esophageal Function Tests in Chinese Patients with Functional Heartburn and Reflux Hypersensitivity

Figure 2

Receiver operating characteristic (ROC) curves for reflux hypersensitivity (RH) and functional heartburn (FH). On ROC analysis, the DeMeester score, total acid exposure, total bolus exposure, and the numbers of proximal total and distal total reflux events yielded areas under the curves of 0.607 (95% CI 0.534–0.680), 0.596 (95% CI 0.522–0.669), 0.671 (95% CI 0.601–0.741), 0.662 (95% CI 0.589–0.736), and 0.697 (95% CI 0.529–0.765), respectively, thus significantly distinguishing RH from FH.
