Controlled trials: allocation concealment, random allocation, and blinding [PDF]
BMJ, 2015 The efficacy of nicotine patches in pregnant women who smoke was investigated using a randomised placebo controlled trial. The intervention was the administration of 16 hour nicotine patches until the time of delivery. Participants were 402 pregnant women older than 18 years who smoked at least five cigarettes a day and whose babies were between 12 and

Researchers investigated the effects of manual lymph drainage on the development of lymphoedema related to breast cancer. A randomised single blinded controlled trial was performed. The intervention was a six months’ treatment programme consisting of guidelines about prevention of lymphoedema, exercise therapy, and manual lymph drainage.

The Home Office and Random Allocation Experiments
Evaluation Review, 2003By examining the history of the random experiment in the Home Office in the United Kingdom, this article demonstrates that research is not an altogether rational process and that fashion, personality, and politics are at least as important as science and evidence when setting research and policy programs and determining methodologies. The article also

Presenting Objects for Random Allocation
SSRN Electronic Journal, 2022AbstractFor random allocation, whether a desirable rule exists or not hinges on the domain of agents' preferences, whose formation is affected by how objects are presented. We hence propose a model studying how to present objects so that the induced preference domain allows for designing a good rule.

Randomized allocation processes
Random Structures & Algorithms, 2001AbstractMany dynamic resource allocation and on‐line load balancing problems can be modeled by processes that sequentially allocate balls into bins. The balls arrive one by one and are to be placed into bins on‐line without using a centralized controller.

Random allocations and probabilistic languages [PDF]
, 1988 This paper introduces a unified framework for the analysis of a class of random allocation processes that include: (i) the birthday paradox; (ii) the coupon collector problem; (iii) least-recently-used (LRU) caching in memory management systems under the independent reference model; (iv) the move-to-front heuristic of self-organizing search.

Random sampling versus random allocation
BMJ, 2011Researchers investigated the effects of providing people with evidence based information about colorectal cancer and screening. A randomised controlled study design was used. The intervention was a brochure that included personalised risk of colorectal cancer, available screening options with possible benefits and harm, plus information on prevention ...

Randomization by minimization for unbalanced treatment allocation
Statistics in Medicine, 2009AbstractMinimization is a dynamic randomization technique that has been widely used in clinical trials for achieving a balance of prognostic factors across treatment groups, but most often it has been used in the setting of equal treatment allocations.
