In Reply: We agree with Ms Greene and colleagues that physicians may have obligations to participate in research and also to encourage patients to enter research even if doing so is somewhat burdensome. We appreciate this addition to our view.
Dr Katz contends that the obligation to participate in research studies can vary depending on the clinical importance of a study. We agree and consider this suggestion to be a refinement and not a negation of the public goods argument that we have made.
