In Reply: We agree with Dr Katz and colleagues
that reciprocity constitutes an additional mechanism through which gifts influence
physicians. As they note, the research findings they summarize reinforce several
of our points, including the conclusion that even small gifts are influential.
Reciprocity is especially important for gift-giving, but the self-serving
bias, which was our focus, plays a role in nearly all conflicts of interest
that physicians face, such as being paid for referring patients to clinical
trials or profiting from procedures that they recommend.
