Among these features are whether assignments are truly made at random, whether the health outcomes of concern are monitored accurately in all participants, and whether a large enough number of such outcomes occur in the participants to yield statistically precise results.
The results of such trials are most directly generalizable to study-eligible patients who would have enrolled and who receive the same interventions provided in the trial setting. However, as Dhruva and Redberg illustrate in this issue of the Archives,2 the demographic profile of a trial's . . . [Full Text of this Article] NATURE OF THE TREATMENT PROTOCOL
