Signal height ratios (SHR) in patient and reference populations
| Study group (n) | PME SHR | PDE SHR |
| Healthy volunteers (n=23) | 1.93 (0.51) | 2.59 (0.60) |
| Biliary duct strictures (n=6) | 2.59 (0.85) | 2.52 (0.79) |
| Good graft function (n=12) | 2.13 (0.61) | 2.44 (0.68) |
| Chronic rejection (n=4) | 3.95 (1.13)** 5-151 | 2.80 (1.12) |
Results are expressed as mean (SD).
5-150 p<0.05, **p<0.01 v healthy volunteers.
↵5-151 p<0.05 v patients with good graft function.
