 Mean integrated oesophageal acidity (IOA) of the reflux events of each individual was calculated and revealed that short acid reflux events were associated with minimal acidity. The cumulative totals of all subjects revealed that, despite having many more events, the short reflux events did not contribute substantially to overall oesophageal acid burden.
