Figure 1 Increment in the detection of elevated AET comparing 1 day of recording to the final results from the 2-day study. An elevation in AET on either recording day was considered abnormal. The difference approached statistical significance when all subjects or those with typical symptoms were considered (*P < 0.1).

Figure 2 Increment in the establishment of reflux-symptom associations from 1 day of recording (solid bars) to the entire 2-day period (solid plus hatched bars) with a comparison of findings between the 2 tests used. The GPE was more likely to identify subjects than the SI by the end of the study (*P = .03 compared to the SI). The increment in positive findings on the GPE for patients with atypical reflux symptoms also was statistically significant at the conclusion of the study (**P = .01 compared to the 1-day results.)
