2. Figure 1
Percent time of pH less than 4 for each day of the 4-day study. A significant reduction in distal esophageal acid exposure occurred within the first day of administration of rabeprazole (day 2) and was maintained throughout the remainder of the recording period. Only 1 patient (6%) failed to normalize acid exposure levels during the treatment phase. The horizontal bars represent the median acid exposure for each day. *Significance at the P < .005 level.

3. Figure 2
Representative 96-hour Bravo pH tracing from a patient with significant GERD on day 1. The shaded regions represent supine periods. Initial esophageal exposure was 10.2% on day 1 and showed an upright reflux pattern. After the administration of rabeprazole at 20 mg orally twice a day, the acid exposure decreased to 2% on day 2, .7% on day 3, and .3% on day 4.
