Esophageal mucosa's exposure to reflux volume during 24 hour period was similar in both ERD and NERD patients. Reflux-related acid exposure (pH drops (pH<4) associated with reflux detected by impedance) and reflux-related alkaline exposure (pH elevation (pH>7) associated with reflux detected by impedance) in ERD patients was higher than in NERD patients.
