|---|---|---|---|
| GER-n (n = 67) | 3.4 ± 1.8 | 9.4 ± 7.1 | 44 ± 27 (8–130) |
| GER-p (n = 134) | 3.4 ± 1.8 | 8.7 ± 5.6 | 45 ± 33 (13–185) |
| GER-pd (n = 30) | 3.6 ± 2.2 | 7.1 ± 1.8 | 35 ± 15 (13–70) |
| GER-pp (n = 104) | 3.4 ± 1.7 | 9.1 ± 6.3 | 48 ± 36 (13–185) |
| PGA-p (n = 31) | 3.0 ± 0.9 | 8.4 ± 5.2 | 60 ± 46 (15–185) |
| Healthy volunteers | 3.3 ± 1.7 (≤6.7) | 6.1 ± 1.7 (≤9.5) | 25 ± 7 (16–38) (≤39) |
Data are mean ± SD. For gastric half-time, range is provided in parentheses. Values for healthy volunteers are based on mean + 2 SDs for all parameters, with normal threshold values provided in parentheses.
