Increased inspiratory esophagogastric junction pressure in systemic sclerosis: An add-on to antireflux barrier

Figure 2 Mean lower esophageal sphincter pressure and minimal respiratory lower esophageal sphincter pressure in particular were significantly lower in systemic sclerosis patients than in healthy volunteers. ^bP < 0.01, ^dP < 0.01 vs healthy. SSc: Systemic sclerosis; LES: Lower esophageal sphincter.
