It is difficult to imagine a physician investigator who does not also at the same time play the role of "physician-friend" in the sense of Dr. Silverman's proposal (Pediatrics, 38:373, 1966). Any physician responsible for the subjects of clinical investigation must perform his role guided by the same ethical considerations that guide other physicians in the care of their patients. Were it otherwise, the subjects would be placed at some jeopardy as to their welfare and the preservation of their dignity.
