Age-related impairment of esophagogastric junction relaxation and bolus flow time

Figure 6 Bolus flow time is reduced during liquid and viscous swallows in asymptomatic older subjects without (older non-cleared) impedance-based esophageal bolus clearance and also in older subjects with esophageal clearance (older cleared) by impedance criteria, when compared to young controls (control). ^aP < 0.05, ^eP < 0.001 vs control; ^fP < 0.001 vs older cleared.
