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.
