Question

Of the following, which represent desirable characteristics that help to minimize bias in the conduct of a clinical trial? Indicate all that apply.: 1.The principal investigator selects which patients enroll in each arm to ensure that a given clinical trial has an equal likelihood of success or failure (equipoise). 2. Double-blinding to ensure that neither participants nor investigators know whether a given study participant is receiving the study drug or not. 3. Concurrent control arms in clinical trials allow researchers to directly compare the effects of the study drug to a placebo or a current standard of care. 4. A study that is as short as possible, since the longer the trial, the more likely extraneous variables will be introduced that obscure product benefit.
