Do medical schools publish the number of students who take research years? I see that many schools post match rates and then match lists, but is there any way to determine how many students opted to forego the match for research? (That is, beyond trying to find the class size and then counting the students who match to determine the remainder, assuming nobody left the program). Also, when looking at a match list, does it include students who graduated from that school the previous year and then took a research year?
