Figure 2 Distal esophageal acid exposure in both groups. A: In the supine position. The median time at pH < 4 in the distal esophagus in the supine position was significantly longer in patients with BE (group A) than in those with GERD without BE (group B) (P < 0.03); B: In the upright position. The median time at pH < 4 in the distal esophagus in the upright position did not differ significantly between patients with BE (group A) and those with GERD without BE (group B).
