TLDR
It is current practice in clinical trials to rely exclusively on either randomized controls or historical controls, but not both, and the methods described provide an objective, quantitative approach for the combination of these two sources of control data and this should lead to a more efficient use of patients in the execution of clinical trials.

Controlled studies in clinical cancer research.

TL;DR: A review of abstracts and papers reporting clinical trials of new anticancer agents reveals that only a small percentage have been controlled, suggesting that continued development of the study-design process and new uses of peer review are needed.

How are randomized study participants placed into control and investigational groups?

In the design of a randomized trial the presence of historical data enables one to enter a reduced proportion of patients into a randomized control group, the precise amount of this reduction depending on the size of the historical data and also its potential bias.
