Irritable bowel syndrome and organic diseases: A comparative analysis of esophageal motility

Figure 2 Amplitudes of the peristaltic waves throughout esophagus. The mean value of amplitudes in patients with SSc was significant lower comparing to subjects with SLE and IBS in the middle (B) and distal (A) esophagus (^bP < 0.01 vs SSc). In the proximal part (C) IBS patients showed higher peristaltic amplitudes in comparison to the other groups (^cP = 0.05 vs SLE). Normal values as previously described. IBS: Irritable bowel syndrome; SLE: Systemic lupus erythematosus; SSc: Systemic sclerosis.
