Esophageal Motility Variables in the 3 Groups, Expressed as Median, Interquartile Range, Both With Water at Room Temperature and Cold Water

^aIn achalasia and non-obstructive dysphagia (NOD) patients contractile front velocity (CFV) was measured in those who showed peristalsis and an identifiable contractile deceleration point, i.e., 4 achalasia, 8 (single swallow [SS]) and 6 (multiple rapid swallows [MRS]) NOD patients; ^b1-minute distal contractile integral [DCI], 1-minute cumulative DCI was calculated during intraesophageal water infusion as a measure of spontaneous esophageal activity.
