Comparison of breath test parameters
| Sumatriptan | Control | P value | |
| T1/2 | 131.84 (103.13-168.70) | 120.27 (89.61-138.25) | 0.0166 |
| Tlag | 80.085 (59.23-125.89) | 61.11 (39.86-87.05) | 0.0125 |
| GEC | 3.545 (3.20-3.97) | 3.55 (3.19-4.03) | 0.6460 |
| β | 2.3374 (1.6407-3.8209) | 2.0847 (1.4755-2.9269) | 0.0284 |
| κ | 0.5833 (0.3689-0.7836) | 0.6180 (0.4661-0.8872) | 0.3329 |
T1/2: Time to emptying of 50% of the labeled meal (min); Tlag: Very similar to the percentage dose recovery peak time (min); GEC: Gastric emptying coefficient; β and κ: Regression-estimated constants. A larger (smaller) value of β indicates slower (faster) emptying in the early phase, and a larger (smaller) value of κ indicates faster (slower) emptying in the later phase.
