Results of 24-hour esophageal pH monitoring. Based on the results, we divided the patients into 3 groups: type A had frequent acid regurgitation (>50 occurrences) and frequent coughing (>30 occurrences), type B had frequent acid regurgitation (>50 occurrences) and infrequent coughing (<30 occurrences), and type C had infrequent acid regurgitation (<50 occurrences) and infrequent coughing (<30 occurrences).
