Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Sugar Pill | Placebo arm~placebo: 400mg/kg/d divided TID for year 1 only. | 1 | 9 | EG000 |
| Group 2 | L-serine | amino acid supplementation with L-serine~L-serine: 400mg/kg/d L-serine or placebo divided TID for year 1, then crossover of placebo arm so that all patients on 400mg/kg/d L-serine divided TID for year 2. | 0 | 9 | EG001 |
