Stratified Randomization

Definition

Health Economics

• A method used in clinical trials to ensure that equal numbers of participants with a characteristic thought to affect prognosis or response to the intervention are allocated to each arm. For example, in a trial of women with breast cancer, it might be used to ensure that there are similar numbers of pre-menopausal and post-menopausal women in each comparison group.
