And this.
As for all this talk about match lists, I wouldn't let that be of concern to you. Match lists are highly dependent upon personal preference, and there is a lot more that factors into people's residency program selection than just school prestige. In particular, geography becomes much more important at the residency application stage, especially since many people get married/start families during med school and residency. Since UMD is a state school, many of the matriculants are from MD and will want to stay in the area for residency for family reasons. The match list will therefore reflect that regional bias. That doesn't mean those students couldn't have done residency OOS if they had wanted.
Even more importantly, you can't find out from a match list the info that you *really* want to know, which is, how many students matched to their top choice program in their top choice specialty? If I ranked IM at UMD first and matched there, that's as successful as a match result gets (top choice program in top choice specialty). But what if I really wanted to do anesthesia in Cali and ended up in IM at JHU, and JHU IM was my twentieth rank? Even though that looks like a great match on paper to a bunch of strangers who don't know how far down my list I had to go, it's not a good match from my perspective because it wasn't the specialty/institution/area of the country I wanted. About the only match result that would be worse would be going even farther down my list or ending up unmatched altogether.
Unfortunately, med schools don't provide applicants with this kind of info. You may be able to feel out some of the MS4s at second looks to get an anecdotal idea of how many got their top matches, but even then, there's no guarantee they'll be honest with you.
