Fig. 1. We classified reflux events according to the temporal association between reflux episodes and supragastric belches (SGBs) into (1) reflux episodes preceded by SGBs: SGBs occurred immediately (1 second) before reflux onset (A), (2) reflux episodes followed by SGBs: SGBs occurred within 10 seconds after a reflux onset (B), and (3) lone reflux: reflux episodes without SGBs occurred during 1 second before and 10 seconds after reflux onset (C).
