Fig. 4. Distribution of the supragastric belching types. Most common belching was isolated belching (IB) in belching disorder (BD), and during belching in gastroesophageal reflux disease (GERD) group. Gastroesophageal reflux related supragastric belching (excluding IB) was significantly higher in GERD group than BD group (P < 0.005). Total preceding belching (PB) before and during reflux events was also significantly higher in GERD group than BD group (P < 0.05). These finding suggest that supragastric belching may have a role in GERD. FB, following belching; DIB, during-isolated belching; DPB, during-preceding belching. Percentage was a mean value of each individual.
