Figure 3 Esophagogastric junction pressure during sinus arrhythmia maneuver is higher in systemic sclerosis patients than in healthy volunteers. This difference is even more pronounced if this parameter is normalized to the degree of inspiratory diaphragm lowering (IDL). aP < 0.05, bP < 0.01 vs Healthy. SSc: Systemic sclerosis; SAM: Sinus arrhythmia maneuver.
