Demographics of patients, grafted and non-grafted. The table shows the age at time of operation (for patients without grafts, the time of surgery is taken as May of the year 2000; which is the average date of the operations of the first four patients) along with their disease characteristics
| Group | Age | M:F | Duration of disease at time of first surgery (years) | Duration of disease at last assessment | UHDRS total motor score at surgery | Last recorded UHDRS total motor score (months after first graft) |
|---|---|---|---|---|---|---|
| Patient 1 | 50 | F | 7 | 17 | 31 | 37 (120 mo) |
| Patient 2 | 52 | M | 9 | 15 | 46 | 58 (108 mo) |
| Patient 3 | 53 | M | 7 | 16 | 32 | 66 (96 mo) |
| Patient 4 | 45 | M | 6 | 15 | 78 | 87 (36mo) |
| Patient 5 | 44 | M | 4 | 10 | 12 | 25 (78 mo) |
| Patients with grafts average | 48.8±14.6 | 4 : 1 | 6.6±0.8 | 14.6±1.2 | 39.8±10.9 | 54.6±10.9 |
| Patients withoutgrafts average | 49.8±2.02 | 8 : 4 | 7.2±2.4 | 14.9±3.5 | 27.9±14.0 | 40.5±19.7 |
It should be noted that the UHDRS motor scores, especially the last recorded scores of the patients without grafts were very variable; ranging from 17 to 79 (maximum score is 124).
