Fig. 2. Numbers of supragastric belches (SGBs) classified as SGBs unrelated to reflux, SGBs within 10 seconds after reflux onset, and SGBs immediately before reflux onset during the study period in the pH-positive (pH+) and pH-negative (pH–) subgroups. The proportion of SGBs subtypes was not significantly different between pH+ and pH– (A), *P < 0.05 total numbers of SGBs during the study period in patients with pH+ vs pH–. Numbers of gastroesophageal reflux episodes classified as reflux episodes preceded by SGBs and reflux episodes without preceding SGBs during the study period in the pH+ and pH– subgroups (B). *P < 0.05 total numbers of reflux episodes during the study period and reflux episodes preceded by SGBs during the study period in patients with pH+ vs pH–.
