Depends on the residency, but regardless, having pubs does help over not having them. Board scores matter more, but good scores + good pubs, can help you get your pick of program even in 'non-competitive' residencies.
This is incorrect. Why would a residency program hold it against someone for being more involved in research for a longer period of time? What you see when you pubmed your name is what counts... it's not like that stuff expires.
I'm not in undergrad (graduated 2010) and my current job is in clinical research, so I'm just milking the experience for what it's worth!
I should have one first author, a few second authors, and a third author publication that made significant alterations to standard of care in a subspecialty.
I'm hoping this stuff gives me a leg up when I try starting research in med school, but it might allow me to concentrate more fully on classes for a bit since I'll already have a head start. Lets see how it goes. I'd like to stay involved in this stuff because I do enjoy it!
