Depreciation rates of treatment effect over time by treatment group.
| Treatment group | Treatment effect duration | Depreciation rate* |
|---|---|---|
| 12 Treatments | 6 months | 50% |
| 9–11 Treatments | 4 months | 33% |
| 6–8 Treatments | 3 months | 25% |
*Depreciation rate is calculated using a 12-month time frame. For example, if treatment effect is assumed to diminish at 6 months, the depreciation rate is calculated as 6 months/12 months = 50%.
