Altman, D.G and Bland, J.M (2005) Treatment allocation by minimisation. BMJ, 330 (7495). p. 843. ISSN 0959-535X
In almost all controlled trials treatments are allocated by randomisation. Blocking and stratification can be used to ensure balance between groups in size and patient characteristics. But stratified randomisation using several variables is not effective in small trials. The only widely acceptable alternative approach is minimisation, a method of ensuring excellent balance between groups for several prognostic factors, even in small samples. With minimisation the treatment allocated to the next participant enrolled in the trial depends (wholly or partly) on the characteristics of those participants already enrolled. The aim is that each allocation should minimise the imbalance across multiple factors.
