Results of the Volunteer Study
| Parameter | Gastric region | Barostat | SPECT | SPECT + PPI | P (SPECT ± PPI) | P (SPECT − barostat) |
|---|---|---|---|---|---|---|
| Fasting | Fundus | 284.07 ± 36.11 | 150.07 ± 6.42 | 150.79 ± 3.78 | NS | <0.01 |
| Postprandial | Fundus | 553.17 ± 53.82 | 339.36 ± 10.76 | 358.75 ± 10.14 | NS | <0.01 |
| Diff | Fundus | 269.10 ± 45.00 | 189.29 ± 10.30 | 207.96 ± 9.50 | NS | NS |
| Ratio | Fundus | 2.200 ± 0.30 | 2.30 ± 0.10 | 2.39 ± 0.07 | NS | NS |
NS = not statistically significant; Diff = difference in volume between mean volume of total postprandial recording period and 15 min before meal ingestion; Ratio = average of 60-min postprandial volume divided by mean fasting volume.
