Design outcomes

Primary

MeasureTime frame
The study was carried with patients who had been diagnosed as having PPI-resistant NERD, showed no erosive esophageal mucosal damage, and showed no alleviation of dysphagia symptoms after administration of standard doses of PPIs for at least 8 weeks. After enrolment, the presence or absence of esophageal motility disorder was evaluated on the basis of the Chicago classification, using HRM.

Secondary

MeasureTime frame
Efficacy of the PPI for NERD
