What is a randomisation list?
A randomisation list determines the order in which treatments will be allocated to subjects. It may be blocked and/or stratified. It does not contain kit codes – these are kept separately in a code list. Randomisation lists are not needed when dynamic methods of allocated are used, such as minimisation.
Sequence | Block | Block size | Treatment |
1 | 1 | 2 | Active |
2 | 1 | 2 | Placebo |
3 | 2 | 4 | Active |
4 | 2 | 4 | Placebo |
5 | 2 | 4 | Placebo |
6 | 2 | 4 | Active |
