24-hour esophageal pH-monitoring in children suspected of gastroesophageal reflux disease: Analysis of intraesophageal pH monitoring values recorded in distal and proximal channel at diagnosis

Figure 5 Summary analysis of total acid GER index and acid GER index (supine position) of 24-h pH-monitoring in 264 children suspected of GERD; pH-monitoring with 1¹- or 2-channel probe. ¹Values of pH-monitoring parameters in group 1 did not undergo comparative analysis with corresponding values in remaining groups.
