Before
N Take-up Treatment 1 Treatment 2 Treatment 3

After
Considering the following take-up:
Control ->100%
Treatment -> 40%
Treatment 2 -> 80%
Treatment 3 -> 95%
Then the MDEs when comparing to the control groups are:
Treatment 1 --> 0,2524 SD
Treatment 2 --> 0,1305 SD
Treatment 3 --> 0,1099 SD
The MDs of the Treatment 2 (SMS) compared to the other treatments:
Treatment 1 --> 0,2822 SD
Treatment 3 --> 0,1430
The MDs of Treatment 3 compared to the Treatment 1 --> 0,2822 SD
