It describes (1) the sources of data; (2) what was known about stroke prevention in 1977; (3) the decision to initiate the EC/IC bypass trial, using a model that suggests relevance and feasibility are important factors in the decision to develop a clinical trial; (4) the peer review of the scientific merit of the grant application and the National Institute of Neurological and Communicative Disorders and Stroke Advisory Council's decision to recommend funding the trial; and (5) conclusions regarding the decisions to initiate and fund clinical trials.
