There is an AAMC Fact page that I can't seem to find now (try to post later) that breaks down each specialty by AOA, board scores, and research. There is a set of columns for those that do and don't publish. There is another set of columns for those that "participate in a research project." Fields like radiology have 90+% of applicants "participating in research." My question is - how does the AAMC define "participating in research?" Does aiding in a case study count as participating in research? Are 90% of rads applicants doing bench research or clinical research? What about a lit. review? Maybe current residents or current applicants (who have seen the residency applications) can shed some light on this too. It just seems like "research" on a CV could be incredibly broad. Thanks for everyone's insight.
